Question

Please someone help me with this!!!

Answer 1

Answer:

a₅ = -3125

Step-by-step 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,

$a_5=-5\times 5^{5-1}\\\\=-5\times 5^4\\\\=-3125$

So, the fifth term is equal to -3125.
