Illustrate an abstract mathematical concept. Depict a balance scale with the numbers 12, 18, and 28, placed on one side, and a large question mark on the other. The question is alluding to the average of those numbers being equal to 21. The scale should be almost balanced, implying that the question mark represents a number close to the counterpart. No text should be included in this image.

If the average of these four numbers is 21, find the missing number.

12, 18, 28, ?

What is the missing number and why

4 * 21 = 84

12 + 18 + 28 = 58

84 - 58 = ?

26!

26

26

Yes!

26!!!

26

12+18+28+x/4=21 58+x=84 x=84-58=26

If the average of these four numbers is 21 find the missing number 12,18,28,_,_,_.
