Question

The nth term of a sequence is `2^n+2^(n-1)`, how do you work out the 10th term of the sequence?

Answer 1

`1536`.

Explanation:

To find the `10^(th)` term of the sequence having `n^(th)` term

`2^n+2^(n-1),` we just plug in `n=10` in the formula for `n^(th)` term.

`:."The reqd. term="2^10+2^(10-1)`,

`=2^10+2^9`,

`=1024+512`,

`=1536`.
