mistakes (Posted on 2013-09-27) Difficulty: 2 of 5
. In an attempt to copy down from the board a sequence of six positive integers in arithmetic progression, a student wrote down the five numbers,

113; 137; 149; 155; 173;

accidentally omitting one. He later discovered that he also miscopied one of them. Can you help him and recover the original sequence?
