Question

Find 3 consecutive even numbers that brings 90

Answer 1

Answer:

Three consecutive even numbers whose sum is 90 are 28,30 and 32

Answer 2

Find 3 consecutive even numbers whose sum is 90.

Given there are 3 consecutive even numbers which add up to give 90.

Let the middle number of the three be  'n'.

Then the other two numbers would be $n-2$ and $n+2$, so let the equation be $(n−2)+n+(n+2)=90$.

$3n-2+2=90$

$3n=90$

$n=\frac{90}{3}$

So the three numbers would be $28$, $30$ and $32$ as, $30-2=28$ and $30+2=32$.
