Question

the G.P whose 3rd and 6th terms are 1,-1/8respectively is​

Answer 1

Answer:

ar^2 =2; ar^5=-1/8

Step-by-step explanation:

formula if GP is

Tn = ar^n-1

3rd term is 1, where n is 3 ; 6th term is -1/8 , where n is 6

so, T3=1. ; so, T6 = -1/8

1=ar^3-1. ; -1/8 =ar^6-1

1=ar^2. ; -1/8 = ar^5
