A snail kite is a kind of bird that eats apple snails. On the first day, a snail kite ate 3 snails. Then it eats 2 more snails than it did the day before. How many apple snails in all did a snail kite eat for 5 days? Let's answer step by step:
On the second day, the snail kite ate 3 + 2 = 5 apple snails. On the third day, the snail kite ate 5 + 2 = 7 apple snails. On the fourth day, the snail kite ate 7 + 2 = 9 apple snails. On the fifth day, the snail kite ate 9 + 2 = 11 apple snails. The snail kite ate a total of 3 + 5 + 7 + 9 + 11 = 35 apple snails in 5. days. The answer: 35.
