Diar Shrey Kumar Dubey, the sum in the equation is the geometric progression with the common ratio r=1/4 and scale factor a=1. Then sum = a/(1-r) = 4/3
Sir how to solve the summation what is the formula cause i am from a non mathematical background. kindly give an alternate method or simplify this one
