The sum of an infinite geometric series is of the form: S=a11−r where a1 is the first term and r is the ratio whose absolute value is less than 1. We know that the second term is the first term multiplied by the ratio. In other words: a1⋅r=1a1=1r Thus, the sum is the...

What is the formula for the sum of infinite geometric series? Where a is the initial value and r is the common ratio: a * (1/(1 - r)) Note that this formula only applies if |r|<1! If this is not the case, then the series diverges. What is the formula of the sum of GP?
The sum of infinite geometric series with initial term {eq}a{/eq} and common ratio {eq}r{/eq} is given by, {eq}\displaystyle \sum_{n=0}^{\infty} ar^n= \frac{a}{1-r}{/eq} We will use this formula to find the final solution. ...

An infinite geometric series is any series that can be written in the form ∑n=0∞a1rn If we write out the first few terms of the series, then we get ∑n=0∞a1rn=a1+a1r+a1r2+a1r3+…=a1(1+r+r2+r3+…) Now, if we call this sum S, ...
