Hi again!

I apologize for the confusion. I had misunderstood your question and tried to show how to calculate the average of all numbers in the square. The middle number is not necessarily the average of all the other numbers. Great observation, though!

Happy Learning,

Thank you Sir. I got it.

I model 3x + 240 = 5x - 350

x = 295

So, Rudy had 5 * 295 = 1475

Thank you
