+489 Laverne starts counting out loud by ${}5$'s. She starts with $2$. As Laverne counts, Shirley sums the numbers Laverne says. When the sum finally exceeds $20,$ Shirley runs screaming from the room. What number does Laverne say that sends Shirley screaming and running?
+1876 We can easily just graph out the numbers since there are not a lot of terms we have to go through.
Laverne | Shirley |
| 2 | 2 |
| 7 | 9 |
| 12 | 21 |
This means when Laverne says 12, Shirley goes off running!
Thanks! :)
