So here's the problem:

The expression for the 14th term of the geometric sequence \({x, x^3, x^5, ...}\) is....

and here are the possible solutions:

A  \({x^{13}}\)

B  \({x^{14}}\)

C  \({x^{27}}\)

D  \({x^{29}}\)

I'm completely stuck! :(

Hmmmm?   Just march them on out.....you can do it...

1st       2nd      3rd     4th        5th .......14th

x          x^3      x^5      x^7       x^9

You probably can see a pattern......   multipy by 2    subtract 1

14 *2 = 28

Subtract 1 = 27

x^27      Not so really bad, huh?   Do you 'get it' ?    Cool!        Math on !
