B (1) = - 500

b (n) = b (n - 1) 4/5

What is the 3rd term in the sequence?

-800

Step-by-step explanation:

First term, B (1) = - 500

nth term, b (n) = b (n - 1) 4/5

comparing with the arithmetic progression equation

T (n) = a (n - 1) d

a = b (1) = b

d = 4/5

Third term = b (3)

n = 3

b (3) = - 500 (3 - 1) * 4/5

b (3) = - 500 (2) * 4/5

b (3) = - 800

it's actually - 320
