Sum of a geometric series
Step-by-step explanation:
1 + 1 • 7 + 1 • 7² +... 1 • 7⁶
1 + 1 • 7 + 1 • 7² +... 1 • 7⁷
7 + 1 • 7 + 1 • 7² +... 1 • 7⁶
7 + 1 • 7 + 1 • 7² +... 1• 7⁷
The expressions above represent the sum of a geometric expression
Sum of a geometric expression=a+ar+ar^2+ar^3+ar^4ar^(n-1)
a=first term
r=common ratio
n=number of terms in the series
Where r is not Equal to 1
