Important Notes on Geometric Progression
In a geometric progression, each successive term is obtained by multiplying the common ratio to its preceding term. The sum of infinite GP formula is given as: Sn=a1−r S n = a 1 − r where |r|<1.
How do you solve a geometric sequence?
To find the sum of a finite geometric series, use the formula, Sn=a1(1−rn)1−r,r≠1 , where n is the number of terms, a1 is the first term and r is the common ratio .
How do you find the nth term in a geometric sequence?
What is the formula for finding the nth term? The nth term of a geometric sequence with first term a and the common ratio r is given by an=arn−1 a n = a r n − 1 .
