Second term of a GP is 1000 and the common ratio is r = 1n where n is a natural number. Pn is the product of n terms of this GP. P6 > P5 and P6 > P7, what is the sum of all possible values of n
Correct option is
according to ques , common ratio is positive and one term is positive which means = all terms should be positive.
1/r = n
n can be 4 or 5 , sum of possible values = 9
so , B is the correct option
