Question

The sum of three consecutive even numbers is 558. What is the 1st number?

Answer 1

Answer:

Let the first number be x

So the second number would be x+2

The third number would be x+4

x+x+2+x+4

3x+6=558

3x=558-6

3x=552

x=186

So the first number is 186

Answer 2

Answer:

First number is 184

Step-by-step explanation:

Let first number be x

so second number be x+2 and third be x+4

x+x+2+x+4=558

3x+6=558

3x=558-6

3x=552

x=552/3

x=184

x+2=186

x+4=188
