Correct Answer - Option 2 : 29
Given :
The number of three consecutive numbers = 87
Calculation :
Let the three consecutive natural numbers be x , (x + 1) , (x + 2)
According to the question,
x + (x + 1) + (x + 2) = 87
⇒ 3x + 3 = 87
⇒ 3x = 87 - 3
⇒ 3x = 84
⇒ x = 28
Middle term = x+1
⇒ 28 + 1 = 29
∴ The middle number is 29.
