What is an arithmetic sequence?

An arithmetic sequence is a sequence of numbers where each term is found by adding a constant value to the previous term. This constant value is called the common difference. The general form of an arithmetic sequence is: a, a + d, a + 2d, a + 3d, ... where 'a' is the first term and 'd' is the common difference.

How do you determine the common difference in an arithmetic sequence?

To determine the common difference in an arithmetic sequence, subtract any term in the sequence from the term that follows it. The result will be the common difference between consecutive terms in the sequence. This difference remains constant throughout the entire sequence and helps in predicting any term in the sequence.

What is a geometric sequence?

A geometric sequence is a sequence of numbers where each term after the first is found by multiplying the previous term by a fixed, non-zero number called the common ratio. This means that each term is a constant multiple of the term that precedes it.

How do you determine the common ratio in a geometric sequence?

To determine the common ratio in a geometric sequence, you divide any term in the sequence by the preceding term. This ratio remains constant throughout the sequence and is what repeats to form the pattern. In mathematical terms, if the geometric sequence is a, ar, ar^2, ar^3, ... then the common ratio, denoted by r, is found by dividing any term in the sequence by the term before it, such as r = (ar^n) / (ar^(n-1)).

How do you find the nth term in an arithmetic sequence?

To find the nth term in an arithmetic sequence, you can use the formula: \( a_n = a_1 + (n-1) \cdot d \), where \( a_n \) is the nth term, \(a_1\) is the first term in the sequence, \(n\) is the position of the term you want to find, and \(d\) is the common difference between consecutive terms. By plugging in these values, you can calculate the nth term of the arithmetic sequence.

How do you find the sum of the first n terms in an arithmetic sequence?

To find the sum of the first n terms in an arithmetic sequence, you can use the formula Sn = n/2 [2a + (n-1)d], where Sn is the sum of the first n terms, a is the first term of the sequence, n is the number of terms, and d is the common difference between the terms. Plug in the values of a, n, and d into the formula to calculate the sum of the sequence.

How do you find the nth term in a geometric sequence?

To find the nth term in a geometric sequence, you can use the formula for the nth term: a_n = a_1 * r^(n-1), where a_n is the nth term, a_1 is the first term, r is the common ratio between consecutive terms, and n is the position of the term you want to find. Simply plug in the values of a_1, r, and n into the formula to calculate the nth term of the geometric sequence.

How do you find the sum of the first n terms in a geometric sequence?

To find the sum of the first n terms in a geometric sequence, you can use the formula: S = a(1 - r^n)/(1 - r), where 'S' is the sum of the first n terms, 'a' is the first term of the sequence, 'r' is the common ratio, and 'n' is the number of terms in the sequence. Simply substitute the values of 'a', 'r', and 'n' into the formula to calculate the sum.

How do you determine if a given sequence is arithmetic or geometric?

To determine if a given sequence is arithmetic or geometric, you can check the differences between successive terms in the sequence. If the differences between consecutive terms are constant, then the sequence is arithmetic. On the other hand, if the ratios between consecutive terms are constant, then the sequence is geometric. By examining these patterns, you can easily identify whether the sequence follows an arithmetic or geometric progression.

How can arithmetic and geometric sequences be applied in real-life situations?

Arithmetic sequences are commonly used in financial applications, such as calculating interest rates on loans or investments where the amount increases or decreases by a constant rate each period. On the other hand, geometric sequences are useful in scenarios involving exponential growth or decay, like population growth, bacterial growth, or radioactive decay. Both types of sequences can assist in predicting future values based on established patterns, helping in budgeting, forecasting, and decision-making in various real-life situations.
