Try our Geometric Sequence Calculator to quickly obtain the Sum of n terms of Geometric Sequence a = 2, n = 10, and r =3 i.e. 59048.0 in the blink of an eye.

## Sum of n terms of Geometric Sequence a = 2, n = 10, and r =3 is 59048.0

Steps to find sum of n terms of geometric sequence:

**sum of n terms of geometric sequence formula:-**

S_{n} = `a*(r^n-1)/(r-1)`

**where:**

- s
_{n}is the sum of n terms - a is first term
- n is total number of terms
- r is common ratio

**Input values are:-**

a = 2

n = 10

r = 3

**Put values into formula**

S_{10} = `a*(r^n-1)/(r-1)`

S_{10} = `2*(3^10-1)/(3-1)`

**S _{10} = 59048.0**

Follow the detailed steps listed below to find the Sum of n terms of Geometric Sequence a = 2, n = 10, and r = 3 to make your calculations faster.

- The initial step is to find out the First Term of Sequence a = 2, Common Ratio r = 3 and n = 10
- Later, substitute the given values in the Sum of n terms in G.P Formula i.e. S
_{n}= a[(r^{n-1})/(r-1)] if r > 1 and r ≠ 1 or S_{n}= a[(1 – r^{n})/(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[(r
^{n-1})/(r-1)] and substitute given values i.e. S_{6}= 2[(3^{10-1})/(3-1)] - Simplifying further we have the Sum of n terms of Geometric Sequence S6= 59048.0.
