WebThe sum of the first n terms of a geometric sequence is called geometric series. Example 1: Find the sum of the first 8 terms of the geometric series if a 1 = 1 and r = 2. S 8 = 1 ( 1 − 2 8) 1 − 2 = 255. Example 2: Find S 10 of the geometric sequence 24, 12, 6, ⋯. First, find r . r = r 2 r 1 = 12 24 = 1 2. Now, find the sum: WebA geometric sequence is a type of sequence in which each subsequent term after the first term is determined by multiplying the previous term by a constant (not 1), which is referred to as the common ratio. The following is a geometric sequence in which each subsequent term is multiplied by 2: 3, 6, 12, 24, 48, 96, ... a, ar, ar 2, ar 3, ar 4 ...

WebA geometric sequence is a sequence where every term bears a constant ratio to its preceding term. This ratio is called the "common ratio". The terms of the geometric sequence are of the form a, ar, ar 2, .... Example: Consider an example of geometric sequence: 1, 4, 16, 64, .... Here, 4/1 = 16/4 = 64/4 = ... = 4. WebWrite an expression for the nth term of the geometric sequence. Then find the indicated term. a_1 = 4, r = \frac {1} {6}, n = 10. find the sum of the geometric sequence 3, 15, 75, 375, _ _ when there are 7 terms. Find the sixth term of a geometric sequence in which a_1 = -7 and r = 3. WebExample 4: Finding Terms in a Geometric Sequence If the third term of a geometric sequence is -12 and the fourth term is 24, find the first and fifth terms of the sequence. Solution: Divide the 4th term by the 3rd term to find the common ratio. The common ratio is 24/(-12) or -2. Substitute 3 for n and -2 for r to find the first term. a n =a 1 ... clou stryker t2
