Question

What is the sum of the first seven terms of the geometric series? 3 12 48 192 ...

Answer 1

Hence, the sum of the given GP is 16347

What is a series?

a series is the cumulative sum of a given sequence of terms. Typically, these terms are real or complex numbers, but much more generality is possible.

How to solve?

we can identify from the given geomertric series.

first term = a(say) = 3

geometric factor of progression = r(say) = 4

Sum of the first 7 terms = a($\frac{r^n-1}{r-1}$)          ,where n is 7

Sum = 3($\frac{4^7-1}{3}$) = 16348-1

       = 16347

Hence, the sum of the given GP is 16347.
