Question

If x is the first of three consecutive even integers, express their sum in terms of x

Answer 1

The sum of the three consecutive even integers;

`3x+6`

Step-by-step explanation:

Given that x is the first of three consecutive even integers.

We can write the three consecutive even integers in terms of x;

`x,x+2,x+4`

The sum of the three consecutive even integers would then be;

`\begin{gathered} S=x+x+2+x+4 \\ S=3x+6 \end{gathered}`

Therefore, the sum of the three consecutive even integers;

`3x+6`
