Just a guess but maybe

it has to be an 8 digit number, as the pattern has two 2 digit numbers, then two 4 digit numbers, then two 6 digit numbers. Next should be two 8 digit numbers
12's repeat twice as the ending, the two 13's, so expect two 14 endings for the 8 digit numbers
the 13 repeats 3 times, so maybe a 4th time
that gives
XY WZ 13 14
Y must be a 1, as it' been a 1 four times
X1 WZ 13 14
X has been 3, 2 3, so maybe back to 2
21 WZ 1314
WZ has been 12 three times, then 22 once. It probably goes three times too
