Question 6
Three consecutive integers add up to 51. What are these integers?

Answer 1

Let the three consecutive integers be x, x+1 and x+2.
According to the question, x+ x+1+ x+2=51
$\Rightarrow 3x+3=51\Rightarrow 3x+3-3=51$ [Subtracting 3 from both sides]
$\Rightarrow 3x=48\Rightarrow \frac{3x}{3}=\frac{48}{3}$ [Dividing both sides by 3 ]
x =16
Hence,first integer = 16,second integer = 16+1=17 and third integer= 16 + 2 = 18.
