Find the sum of the first five terms of the geometric sequence: - 1, - 6, - 36

irakobra [83]

The sum of the first five terms of the geometric sequence is -1555

<h3>Sum of geometric sequence</h3>

The formula for calculating the sum of geometric sequence is expressed as:

$S_n=\frac{a(r^n-1)}{r-1}$

where

r is the common ratio = 6/1 = 6

a is the first term = -1

n = 5 (number of terms)

Substitute

$S_5=\frac{-1(6^5-1)}{6-1}\\S_5=\frac{-7776+1}{5}\\S_5=-1555$

Hence the sum of the first five terms of the geometric sequence is -1555
