x+x^2+x^3+x^4... = 14

Find x

Could someone please provide an explanation on how to solve this?

The formula for infinite geometric series is ##\displaystyle \sum_{n=0}^\infty a_n x^n =\frac{a_0}{1-x} ##. But this is true only for ## -1 < x < 1##. Just use this on the series to get an equation in a familiar form.
