# Waldo's Peanuts

Waldo ate a total of 100 peanuts in 5 days. Each day, he ate 6 more peanuts than he did the day before. So, how many peanuts did Waldo start with on the first day?

### Hint

Example; if Waldo started with 20 peanuts on day 1, he should have eaten 26 peanuts on day 2. By then, he would have eaten a total of 46 peanuts in 2 days. 20 is not the correct answer though, because by day 5, he would have eaten 160 peanuts.### Answer

Waldo ate 8 peanuts on day 1. He had 14 peanuts on day 2 and added 6 peanuts each day up to day 5. By day 5, Waldo would have eaten a total of 100 peanuts.Hide Hint Show Hint Hide Answer Show Answer
