Answer:
8
Explanation:
Let the AP numbers be: ( a - 3d ), ( a - d ), a, ( a + d ), ( a + 3d )
We are given that sum of all these numbers is 40.
⇒ a - 3d + a - d + a + a + d + a + 3d = 40
⇒ 5a + 4d - 4d = 40
⇒ 5a = 40
⇒ a = 40 / 5 = 8
We know that the middle term of the five numbers given is 'a'.
As a result, the given AP's middle term is 8.
