Question

Please someone help me with this!!!

Find the indicated term of the given geometric sequence.

a1 = –5, r = 5, n = 5

Answer 1

a₅ = -3125

Explanation:

Given that,

a₁ = -5, r = 5 and n = 5

The geometric sequence is given by :

`a_n=a_1\cdot r^(n-1)`

Put all the values,

`a_5=-5* 5^(5-1)\\\\=-5* 5^4\\\\=-3125`

So, the fifth term is equal to -3125.
