Question

The numbers 2, 3, 5, 7, and 13 are placed on a number line. For any integer x, its "remoteness" is the sum of the squares of its distance to each of the five numbers. For example, the remoteness of 10 is 8² + 7² + 5² + 3² + 3² = 156. What integer has the smallest remoteness?

Answer 1

I would say 7. When you square the distances the square grow more quickly than the difference of number. So you must have number which is not to far from all the others

Answer 2

If you would have done your homework last night instead of this morning you'd already be done.
