Question

How many rays are in the next two terms in the sequence?

Answer 1

The sequnce is

2, 3, 5, 9, ....

this sequence follows the next formula:

`a_n=2^(n-1)+1`

where an is the nth term.

`\begin{gathered} a_1=2^(1-1)+1=1 \\ a_2=2^(2-1)+1=3 \\ a_3=2^(3-1)+1=5 \\ a_4=2^(4-1)+1=9 \\ a_5=2^(5-1)+1=17 \\ a_6=2^(6-1)+1=33 \end{gathered}`

The next two terms are 17 and 33
