lLet three consecutive integers be x,x+1 and x+2
Three consecutive integers add up to 51.
x+x+1+x+2 = 51
3x+3 = 51
3(x+1) = 51
x+1 = 51/3
x+1 = 17
x = 17-1
x = 16
x = 16
x+1 = 16+1 = 17
x+2 = 16+2 = 18
The three consecutive integers are 16,17 and 18

Answer:
Let the three consecutive integers be x, x + 1 and x + 2.
As per the condition, we get
x + (x + 1) + (x + 2) = 51
⇒ x + x + 1 + x + 2 = 51
⇒ 3x + 3 = 51
⇒ 3x = 51 – 3 [transposing 3 to RHS]
⇒ 3x = 48
⇒ x = 48 ÷ 3 [transposing 3 to RHS]
⇒ x = 16
Thus, the required integers are 16, 16 + 1 = 17 and 16 + 2 = 18, i.e., 16, 17 and 18
Hope it's help you.....❤️
