Answer:
Our fourth number is 52.
Step-by-step explanation:
Let our first even number be <em>x</em>.
Then the second even number must be (<em>x</em> + 2), the third (<em>x</em> + 4), fourth (<em>x</em> + 6), and the fifth (<em>x </em>+ 8).
They sum to 250. Hence:

Solve for <em>x</em>. Combine like terms:

Subtract 20 from both sides:

And divide both sides by five. Hence:

Thus, our sequence is 46, 48, 50, 52, and 54.
Hence, our fourth number is 52.
