I BELIEVE IT IS 156 THE SMALLEST NUMBER 4 AND 6 GO INTO IS 12 12 X 13 = 156
13 and 14
4x(4+sqrt(4))/sqrt(4) ======== 2nd Answer: The above would not equal 13. It would equal 12. 4*(4 + 41/2) / 41/2 = 4 * (4 + 2) / 2 = 4 * 6 / 2 = 12. However, if using powers is acceptable (such as square roots above) then a possible answer would be: 4 + 4 + 4 + 40 = 13
Seems to be +2, +4, +6, +2, +4, +6, etc etc
It is 11.5
