Question

Sum of three consecutive integers is ${}^{\prime }{18}^{\prime }$. Find the numbers.

Answer 1

Let the three consecutive number is $x,x+1$ and $x+2$

Then, According to the given question.

$x+(x+1)+(x+2)=18$

$3x+3=18$

$3x=15$

$x=5$

Then,

$x=5$

$x+1=5+1=6$

$x+2=5+2=7$

Hence, this is the answer.
