Question 832261
x the first number
(x + 1) the second number
x + (x + 1) <= 60
2x + 1 <= 60
add -1 to each side
2x <= 59
divide each side by 2
x <= 59/2
x <= 29 1/2
Since x needs to be a whole number,
the largest value for x is 29.
The pair 29, 30 works.
Other possibilities
1,2
2,3
3,4
and so forth.
