Removing one number makes the average drop from 20. So you can cross out any number below 20 right off the bat.

C) 26, didn’t watch the video but it’s easy. 3x18=54, 4x20=80, 80-54=26.

Did it in my head. Removed one of the 20s and multiplied the 2 difference by the 3 remaining so 26 total is missing

I got C within seconds because the only thing that would bring it down 2 is a number that was over 20 but not too far over and that is from winging it my whole life.

How about the 4 numbers add up to 80. The three numbers add up to 54. 80-54=26. Stop making things so difficult.

The average went down so the number removed needs to be higher than 20. Already made my guess a 50/50 chance

You moved the X,Y,Z to the other side of the equal sign but only changed the sign of X??

@ma9ric: Value has to be greater than 20 if the average drops. 30 doesn’t divide by 4 in whole numbers

Maybe I see things different but if 20-18 is 2. If there were 4 numbers, then 3. 3x2=6 plus the 20
