Given:

If the sum of three consecutive numbers is more than the middle number by 130, then the middle number is.

Formula used:

Let the three consecutive numbers be (n-1), n, (n+1).

Sum of three consecutive numbers = (n-1) + n + (n+1)

Calculation:

(n-1) + n + (n+1) = 3n

3n = n + 130

⇒ 3n - n = 130

⇒ 2n = 130

⇒ n = 130/2

⇒ n = 65

∴ The correct answer is option (2).
