Question

The sum of three consecutive even integers if the first integer is x

Answer 1

3x + 6

Explanation:

If the first even integer is x, the next consecutive even integer is x + 2

The next consecutive integer is x + 4

So sum = x + (x +2) + (x +4) = 3x + 6

You can check this by plugging in some value for x

Say x = 8, Next consecutive even integer = 10 and the next one after that is 12. So sum = 8 + 10 + 12 = 30

Using the formula, 3x + 6 = 3 x 8 + 6 = 24 + 6 = 30

Answer 2

x = first consecutive even number x + 2 = second consecutive even number x + 4 = third consecutive even number

I hope this helps!
