Question

There are □ terms in the sequence 1,2,2

Answer 1

There are exactly 81 terms in the sequence.

Start counting with 1 (like non-computer people).

First term is
`1=2^0`.

Second term is
`2=2^1`.

Third term is
`2^2`.

Fourth term is
`2^3`.

In general the i-th term is
`2^(i - 1)`.

Hope this helps :)
