Hint 3 of 3
Count off the animals in fives and see which spot the 14th lands on.
Show solution
Approach: count in groups of five and find the matching spot
- The five animals always come out in the same order, then start over.
- Animals 1 to 5 are one full group, and animals 6 to 10 are the next full group.
- After 10 we start again: the 11th is the 1st animal, the 12th is the 2nd, the 13th is the 3rd, and the 14th is the 4th animal.
- The 4th animal in the order is the frog (A).
