Question

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

Answer 1

Answer:

The sum of the three consecutive even integers;

$3x+6$

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;

$3x+6$
