Sum of three consecutive numbers is 81 find out the numbers.

Answer»

Let First number = x

Second number = x + 1

Third number = x + 2

Sum of three numbers = 81

∴ According to question,

x + x + 1 + x + 2 = 81

⇒ 3x + 3 = 81

⇒ 3 = 81 – 3, (shifting)

⇒ x = 78/3 = 26

First number = 26

Second number = 26 + 1 = 27

Third number = 26 + 2 = 28
