Question

Which term of the G.P is 2, 6, 18, 54,.......... is 2×310 ?​

Answer 1

Step-by-step explanation:

G.P is 2, 6, 18, 54,.......... is 2×310

a = 2, r= 3 and A_n = 2×310

A_n=ar^n-1

2×310 = 2×3^n-1

Then : 310 = 3^n-1 So

The 2×310 is not a term of this GP

Answer 2

we know,an=ar^(n-1)

(G.P)

therefore,2×3^10 is 11th term
