What is the sum of the first 12 terms of the geometric series below 1/2+2+8+32+

Georgia [21]

∴ $\frac{1}{2} +2+8+32.......12^{th}term$ =2796202.5

Step-by-step explanation:

First term(a) = $\frac{1}{2}$ common ratio(r) = $\frac{2}{\frac{1}{2} }$ =4

n= 12

$S_{n}=\frac{a(r^n-1)}{(r-1)}$

$S_{12}=\frac{\frac{1}{2}(4^{12}-1) }{4-1}$ =2796202.5

∴ $\frac{1}{2} +2+8+32.......12^{th}term$ =2796202.5
