Question

A sequence can be generated by using an=2a(n-1). If a1= 0.25, what is the value of a10?

Answer 1

128

Explanation:

The first term is 0.25 so if you plug that into the equation it is 2(0.25)m which is 0.5 and if you were to continue inputting what you get for each input like 2(0.5)=1 then you would get to a10=128.
