+1348 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?
+37146 For YOUR problem : 2 then 7 then 12 = 21 so the number must be 12 ....but I have no idea what Shirley's problem is !
