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

Feb 14, 2017

See explanation.

#### Explanation:

To calculate the $n - t h$ term of a sequence you substitute $n$ in the formula. So:

${a}_{\textcolor{red}{1}} = {2}^{\textcolor{red}{1}} = 2$

${a}_{\textcolor{red}{2}} = {2}^{\textcolor{red}{2}} = 4$

${a}_{3} = {2}^{3} = 8$

${a}_{4} = {2}^{4} = 16$

and ${a}_{5} = {2}^{5} = 32$
