Homework Help: Math

Posted by Joe on Tuesday, February 16, 2010 at 8:14pm.

The week before a big concert, five friends (Alvin, Bert, Chip, Dennis, and Ethan) stood in line to buy tickets. There were other people between them, but the five friends were in line in the order listed above.

The line was really long, and they were pretty bored. Chip noticed that if he counted the number of strangers between each pair of friends, he got the numbers 7, 12.19, 21 36, 43, 55, 57, 64, and 76. Like I said, he was REALLY bored.

He sent the information to Ethan in a text message, and Ethan passed the time in line using Chip's information to determine how many people were between Alvin and Bert, between Bert and Chip, betwen Chip and Dennis, and between Dennis and Ethan. What did he find?
