what numbers can i use to add up to 34. i have to use 4 numbers to get 34. 1-16 are the numbers?

Answer 1

If you are talking about a "magic square" where all the numbers 1 to 16 are used exactly once and all the rows, columns and diagonals add up to 34, then here is one of many possible answers:

12 .6. 15 .1.
13 .3. 10 .8.
.2. 16 .5. 11
.7. .9. .4. 14
