1.	How many terms are there in 2,4,8,16……1024?
Answer» Clearly 2,4,8,16……..1024 form a GP. With a = 2 and r = 4/2 = 2. Let the number of terms be n . Then 2 x 2^n-1 =1024 or 2^n-1 =512 2^n-1= 2⁹. n - 1 = 9 or n = 10.

Answer»

Clearly 2,4,8,16……..1024 form a GP. With a = 2 and r = 4/2 = 2.

Let the number of terms be n .

Then 2 x 2^n-1 =1024 or 2^n-1 =512

2^n-1= 2⁹.

n - 1 = 9 or n = 10.
