Question

1.) Formula of G. P and also tell me what is a, r

2.) Formula of Sum of n terms of G. P.

​

Answer 1

HII YOUR ANSWER IS HERE

Sum of G.P. up to n terms if 1st term is a and

common ratio is r .

Sn =a.(1-r^n)/(1-r)………….(1) while r < 1 .

or

Sn =a.(r^n -1)/(r - 1)………(2) while r > 1 .

Sum up to infinite terms = a/(1-r) . An

Answer 2

Formula of GP: The nth term of a GP series is Tn = arn-1, where a = first term and r = common ratio = Tn/Tn-1) . The sum of infinite terms of a GP series S∞= a/(1-r) where 0< r<1. If a is the first term, r is the common ratio of a finite G.P.

R value in math: In statistics, the correlation coefficient r measures the strength and direction of a linear relationship between two variables on a scatterplot. The value of r is always between +1 and –1. To interpret its value, see which of the following values your correlation r is closest to: Exactly –1.

Formula of Sum of n terms of GP: The sum of infinite terms of a GP series S∞= a/(1-r) where 0< r<1. If a is the first term, r is the common ratio of a finite G.P. consisting of m terms, then the nth term from the end will be = arm-n. ... with the last term l and common ratio r is l/(r(n-1)) .
