well a term in a geometric series is \[a_{n} = a_{1} r^{n 1}\] you have the 1st term 2 you need to find the common ratio r... is can be done by comparing terms \[\frac{a_{2}}{a_{1}} = \frac{a_{3}}{a_{2}}\] hope this helps

each term is being multiplied by 4 so term 2 = 4 x term 1 8 = 4 x 2 if its correct try it with term 3 term 3 = 4 x term 2 32 = 4 x 8 is it correct.. hope this helps...
