Question

Write the first five terms of the geometric sequence with a1=-2 and common ratio r=-5/2

Answer 1

Answer:

option D

Step-by-step explanation:

First term is -2

common ratio = -5/2

To get second term we multiply first term -2  by common ratio -5/2

$-2 * \frac{-5}{2} =\frac{10}{2} = 5$

To get third term we multiply second term 5  by common ratio -5/2

$5 * \frac{-5}{2} =\frac{-25}{2}$

To get fourth term we multiply third term -25/2  by common ratio -5/2

$\frac{-25}{2}*\frac{-5}{2} =\frac{125}{4}$

Option D is correct
