. 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?

ANS:  YES<o:p></o:p>

WAS 113; 137; 149; 155; 173;<o:p></o:p>

SHOULD BE:             113;    125(NEW) ;   137;   149;   161(CORRECTED);173.
