If there is 1 child, there can be 0 interactions.
1 answer:
Find the differences:
3-0 = 3
9-3 = 6
18-9 = 9
The differences increase by the previous difference plus 3
So 5 kids would have 9+3 = 12 + 18 = 30 interactions.
6 kids: 30-18 = 12 +3 = 15 + 30 = 45 interactions.
7 kids: 15+3 = 18 + 45 = 63 interactions.
8 kids: 18 +3 = 21 + 63 = 84 interactions.
9 kids: 21+3 = 24 + 84 = 108 interactions.
The answer is d. 108
