Determine the missing number in the right figure on the basis of the numbers arranged in the left figure.
I have tried every thing from squares, cubes, products, sum, differences; alternate application of these methods, etc. but cannot at all come close to the options:
(1) 30 (2) 58 (3) 160 (4) 32
I am usually good at these problems but can't solve this one. Please help!
