Try our Geometric Sequence Calculator to quickly obtain the Sum of n terms of Geometric Sequence a = 4, n = 7, and r =4 i.e. 21844.0 in the blink of an eye.
Sn = `a*(r^n-1)/(r-1)`
a = 4
n = 7
r = 4
Put values into formulaS7 = `a*(r^n-1)/(r-1)`
S7 = `4*(4^7-1)/(4-1)`
S7 = 21844.0
Follow the detailed steps listed below to find the Sum of n terms of Geometric Sequence a = 4, n = 7, and r = 4 to make your calculations faster.
1. How to find the Sum of n terms in G.P?
Sum of n terms in G.P can be found by using the formulas Sn = a[(rn-1)/(r-1)] if r > 1 and r ≠ 1 or Sn = a[(1 – rn)/(1 – r)] if r < 1 and r ≠ 1.
2. What is the sum of n terms in Geometric Sequence a = 4, n = 7, and r =4?
