KeyWord = y is a multiple of 17 => 0,17,34, 51

x is equal to the sum of the squares of two distinct prime numbers
4+9 = 13
4+25 = 29
4+49 = 53
9+25 = 34

34-34

Stem: x,y = ints < 60, what is x-y?
x= 1st pn²+next pn², y=17Q

Plug in numbers...
y=17, 34, 51
Anything higher is >60
2 as first number:
4+9 = 13, 4+25 = 29, 4+49 = 53
3 as first number:
9+25 = 34
9+49 = 58
Anything higher is >60

34 should immediately pop out as being a possible value of both x and y, thus x-y could = 0, C. Re: x and y are integers less than 60 such that x is equal to the sum of t   [#permalink] 12 Mar 2019, 12:01
