Question

for an AP five times the 5th teem is equal to eight times the 8th yerm. find the 13th term of the AP

Answer 1

The gap between three terms is 90, so the gap between individual terms is 30. That gives us 30n. The offset appears to be -130, so 30n-130.

So, to the first five terms:

Term 1: 30–130=-100

Term 2: 60–130=-70

Term 3: 90–130=-40

So, -100 + -70 + -40 = -210
