Well, I just try it: 2 plus 2 is 4 4 plus 4 is 8 8 plus 8 is 16 >> +2 , +4, +8 Now it's getting less again 16 plus 4 is 20 20 plus 2 is 22 And the next will be plus 4, because it's getting "more" again? 22 plus 4 is 26 <<< Answer 26
36. 4 squared is 16...16 + 20 - = 36.
9 - 20 / 4 + 16 = 9 - 5 + 16 = 20
94-105= -11 16-20= -4 -11+(-4)= -15
4 + 16 = 20
4x + 4 = 20 4x = 16 x = 4
2x + x + 4 +2x = x + 20 5x + 4 = x + 20 5x - x = 20 - 4 4x = 16 x = 4
