Sum of n terms of Geometric Sequence a = 3, n = 11, and r =5 is 36621093.0
Steps to find sum of n terms of geometric sequence:
sum of n terms of geometric sequence formula:-
Sn = `a*(r^n-1)/(r-1)`
where:
- sn is the sum of n terms
- a is first term
- n is total number of terms
- r is common ratio
Input values are:-
a = 3
n = 11
r = 5
Put values into formula
S11 = `a*(r^n-1)/(r-1)`
S11 = `3*(5^11-1)/(5-1)`
S11 = 36621093.0
Follow the detailed steps listed below to find the Sum of n terms of Geometric Sequence a = 3, n = 11, and r = 5 to make your calculations faster.
- The initial step is to find out the First Term of Sequence a = 3, Common Ratio r = 5 and n = 11
- Later, substitute the given values in the Sum of n terms in G.P Formula i.e. 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
- As in the given case common ratio r is greater than 1 we will use the formula Sn = a[(rn-1)/(r-1)] and substitute given values i.e. S6 = 3[(511-1)/(5-1)]
- Simplifying further we have the Sum of n terms of Geometric Sequence S6= 36621093.0.
