Question

(1) Find the sum of first 15th term of the G.P. 5,5,5,...

(2)If x bar =M=M0 then write type of skewness?​

Answer 1

Given :  the G.P. 5,5,5,...

To Find :  sum of first 15th term

Solution:

G.P. 5,5,5,...

a = 5

r =  1

n = 15

as r = 1   Hence Sₙ  = a(rⁿ - 1)/(r - 1)  can not be used  as  its 0/0 form

sum of first 15 terms  = 15 * 5  = 75
