The answer
The answer to yesterday's question is A9, asdougs rapidly worked out. The numbers are squares in hexadecimal notation; the first three are therefore 1, 4, and 9, followed by 10 (= 16), 19 (= 25), 24 (= 36), 31 (= 49), 40 (= 64), 51 (= 81), 64 (= 100), 79 (= 121), and 90 (= 144). The next is 169 in base 10 which translates to A9 in base 16, A being the usual notation for the number next after 9. crumpetsfortea was nearly there, but dougs nailed it.
drplokta asks in response what comes next in this series:

Obvious when you know why.
