Ok, let's say this is the setup:
Cell B5 = 25
Cell E5 = 15
Cell F5 = 30
Cell G5 = 28
Cell D5 is unknown
I want B5 to represent the average of Range("D5:G5").
What function do I put in Cell D5?

Thanks,

Huh? This is circular and cannot work as you described. You cannot
"derive Q4 by summing...and subtracting the result from Q4"

Explain further?
