Step-by-step explanation:

It gas geometric sequence,

We has a sequence: 1, 2, 4, 8, 16, 32, 64.

It can be solved by two method either sum these digits individually or use formula of sum of geometric sequence

We have formula:

Here r = Common Ratio = 2 ÷ 1 = 4÷2 = 2

and a = First term = 1

⇒

exa:

)

3+11

step-by-step explanation:
