2 numbers that have a difference of 62

Question

out of 34, 25, 4, -13, -17, -37 what are the 2 number that have a difference of 62

Answer 1

Try different pairs, performing subtraction. Example: 4 - (-13) = 4  + 13 = 17; this is NOT THE DESIRED PAIR.

Keep trying.

Answer 2

It sometimes helps to plot the numbers on the number line (or picture it in your head):

       -37                -17    -13           4                    25               34

- - - - x - - - - - - - - x - - -x - - - - - x - - -  - - - - - x - - - - - - - x - - - - - - -

 

And to picture a distance of 62:

  - - - - - - x - - - - - - - - - - - - - - - -- - - - - - - x - - - - - - - -     [note: not to scale]

 

Now, from -13 to 4 is only 17.

-17 to 4 is only 21.

We need something much bigger.

 

Starting at -37, that would be (-37)+62 = 25      Yes !!

 And,    (-17)+62 = 45, which is already beyond the last number.
