Question

the sum of three consecutive even numbers is 144 . find them
​

Answer 1

Answer:

An even number is a multiple of 2, then can be written as 2n. The next even number after 2n is 2n+2 and the following is 2n+4.

So you are asking for which value of n it you have

(2n)+(2n+2)+(2n+4)=144

I solve it for n

6n+6=144

n=1386=23.

The three numbers are

2n=2⋅23=46

2n+2=46+2=48

2n+4=46+4=50
