7-4=3 (difference of 3 sweets given)

For a difference of 3 sweets, total sweets needed:

17-2=15

15 sweets need for each friend having 3 more sweet, hence the number of John friend:

15/3=5

If John give each friends 4 sweets:

5x4=20

However John is short of 2 sweets (needs 2)

20-2=18

Therefore, John has 18 sweets
