Question

Find the 10th and nth term of GP. : 5, 25, 125, .....

Answer 1

Hi ,

Let a and r are first term and common

ratio of a G. P ,

nth term = an = ar^n - 1

Here ,

Given G.P : 5 , 25 , 125 ,...

a = 5 ,

r = a2/A1

r = 25/5 = 5

Therefore ,

a = 5 , r = 5 , n = 10

a10 = 5 ( 5 )^ 10 - 1

= 5 × 5^9

= 5^10
