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 100, Shirley runs screaming from the room. What number does Laverne say that sends Shirley screaming and running?
So Laverne starts at 2, we can count with her and find the sum of all the numbers as we go.
2, 7, 12, 17, 22, 27, 32, 37, 42, 47. We know she will stop here because 2 50's is 100. Lets add the number up now,
2, 9, 21, 38, 60, 87, 119.
So now we know that the first number in the sum to go over 100 is 119, so the answer is 119
