The sum of infinite, i.e. the sum of a GP with infinite terms is S∞= a/ (1 – r) such that 0 < r < 1. geometric sequence. 512, 384, 288,… Step 1 Find the value of r by dividing each term by the one before it. 512 384 288 The value of r is 0.75.
Note: A slightly different form is the geometric series, where terms are added Series and sequence are the concepts that are often confused. Suppose we have to find the sum of the arithmetic series 1,2,3,4100. We have to just put the values in the formula for the series. Let us memorize the sequence and series formulas. Types of Sequence.

Suppose, for example , This lesson will work with arithmetic sequences, their recursive and explicit formulas and finding terms in a sequence. In this lesson, it is assumed that you know A geometric sequence goes from one term to the next by always multiplying (or dividing) by the same value.
One of them is by using a recursive formula.

Similarly, the 1st term of a geometric sequence is in general independent of the common ratio. So clearly this is a geometric sequence with common ratio r = 2, and the first term is a = . To find the n -th term, I can just plug into the formula a n = ar ( n – 1) : a n = (1/2) 2 n –1 = (2 -1 )(2 n –1 ) Given a geometric sequence with the first term a 1 and the common ratio r , the n th (or general) term is given by. a n = a 1 ⋅ r n − 1 . Example 1: Find the 6 th term in the geometric sequence 3, 12, 48, . a 1 = 3, r = 12 3 = 4 a 6 = 3 ⋅ 4 6 − 1 = 3 ⋅ 4 5 = 3072.

Example. Show that the sequence 3, 6, 12, 24, … is a geometric sequence, and Geometric sequence. To recall, an geometric sequence or geometric progression is a sequence of numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio. Thus, the formula for the n-th term is. where r is the common ratio. A geometric sequence can be defined recursively by the formulas a 1 = c, a n+1 = ra n, where c is a constant and r is the common ratio.
