Question

How do you write the first five terms of the sequence `a_n=2^n`?

Answer 1

See explanation.

Explanation:

To calculate the `n-th` term of a sequence you substitute `n` in the formula. So:

`a_color(red)(1)=2^color(red)(1)=2`

`a_color(red)(2)=2^color(red)(2)=4`

`a_3=2^3=8`

`a_4=2^4=16`

and `a_5=2^5=32`
