Question

in an AP the sum of its first n terms is 6 and minus and Square find its 25th term

Answer 1

Hey user !!

Here is your answer !!

⭐________________________________________⭐

Given -

First term (a) = -6

common difference (d) = 5/4

We know that nth term of AP is a+(n-1)d

a25 = -6 + (25-1) (5/4)

a25 = -6+6(5)

a25 = -6+30

a25 = 24

Hope it is satisfactory :-)
