Step-by-step explanation:

We know that the mean of 6 numbers is 24. This means that

$\frac{x}{6} = 24$

Solve for x.

x = 144

If we add, x, (x+2), and (x-2). We will have 9 terms. The value of mean will change to 30. This also means that

$\frac{270}{9} = 30$

144 + x + (x + 2) + (x - 2) = 270

3x + 144 = 270

3x = 126

x = 42
