How to Calculate Sum of first n terms in a finite GP?
Sum of first n terms in a finite GP calculator uses Sum of First n terms=(First term*((Common Ratio^value of n)-1))/(Common Ratio-1) to calculate the Sum of First n terms, Sum of first n terms in a finite GP is the total of first n terms of geometric progression having finite number of terms in it. For eg- 2,4,8,16,32,64. This GP with common ratio 2 has 6 terms in it and sum of its first 3 terms is 14. . Sum of First n terms and is denoted by S_{n} symbol.
How to calculate Sum of first n terms in a finite GP using this online calculator? To use this online calculator for Sum of first n terms in a finite GP, enter First term (a), Common Ratio (r) and value of n (n) and hit the calculate button. Here is how the Sum of first n terms in a finite GP calculation can be explained with given input values -> 1 = (1*((2^1)-1))/(2-1).
