Let x be the number of boys, then,
(3*x*18+x*y)/(3x+x)=17
(54+y)/4=17
y=14 points each boy.
If the average of the two integers is x, the product of the two integers is
(x-1)(x+1) = 440
x² - 1 = 440
x² = 441 = 21²
21 is the odd integer between the two even integers you seek.
The integers are 20 and 22.
