Question

Complete the magic square
numbers from 7 to 21', given that the
Magic Constant = 14*3=42
​

Answer 1

Answer:

As you can see all the rows add up to 15. Notice that each number from 1 to 9 is used once. If you could repeat numbers, many magic squares would become trivially easy, like a grid made entirely of 1s that added up to 3! ... This is the smallest sum possible using the numbers 1 to 16.
