## Sum of n terms of Geometric Sequence a = 4, n = 10, and r =4 is 1398100.0

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 = 4

n = 10

r = 4

Put values into formula

S10 = a*(r^n-1)/(r-1)

S10 = 4*(4^10-1)/(4-1)

S10 = 1398100.0

Follow the detailed steps listed below to find the Sum of n terms of Geometric Sequence a = 4, n = 10, and r = 4 to make your calculations faster.

• The initial step is to find out the First Term of Sequence a = 4, Common Ratio r = 4 and n = 10
• 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 = 4[(410-1)/(4-1)]
• Simplifying further we have the Sum of n terms of Geometric Sequence S6= 1398100.0.
