Given : The product of first three terms of a GP is 125.
To find : It's second term
Solution :
We know that a geometric progression is a sequence of numbers in which common ratio between two consecutive terms is always same.
Let's assume that the first three terms of GP be a/r, a and ar where a is first term and r is common ratio.
Now, according to the question :-
=> a/r × a × ar = 125
=> a × a × a = 125
=> a³ = 5³
=> a = 5
Therefore second term of the GP = a = 5.
