How do you write the first five terms of the sequence a_n=(1/2)^n?

Aug 29, 2017

The first five terms are $\frac{1}{2} , \frac{1}{4} , \frac{1}{8} , \frac{1}{16} , \frac{1}{32}$.

Explanation:

Remember that the first term is $n = 1$.

${a}_{1} = {\left(\frac{1}{2}\right)}^{1} = \frac{1}{2}$

${a}_{2} = {\left(\frac{1}{2}\right)}^{2} = \frac{1}{4}$

${a}_{3} = {\left(\frac{1}{2}\right)}^{3} = \frac{1}{8}$

${a}_{4} = {\left(\frac{1}{2}\right)}^{4} = \frac{1}{16}$

${a}_{5} = {\left(\frac{1}{2}\right)}^{5} = \frac{1}{32}$

Hopefully this helps!
