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).
