# Weird Sequences [closed]

Found this weird sequence: $$8110423, 259974, 9814143, 5512166, 113322, ?$$

The possible answers are:

a) $$334455$$, b) $$7911132$$, c) $$9841233$$, d) $$872236$$.

The correct answer is b), but I can't figure out why, and no explanation was given. Any ideas?

## 1 Answer

The sum of first two digits and the last two digits as a two digit addition gives the rest of the number (middle).

• I see. It is not a sequence, it is a common property you were looking for. – Florian F Jul 10 '20 at 22:16
