Question

2,2root2,4 are in G.P then which term is 64

Answer 1

Answer:11th term

Step-by-step explanation:

2,2root2,4,4root2,.........

First term=a=2

Common difference =r=root2

n th term =a(r)^(n-1)=2(root2)^(n-1)=64

(Root 2)^(n-1)=32

WKT 32=2^5=(root2)^10 .i.e...(root2)^(n-1) =(root2)^10

n-1=10

Therefore,n=11
