A number is arranged in a pattern like: 12345678910111213141516...
What is the lowest value of that pattern divisible by 72?
They are single numbers, not seperate (i.e. first in sequence is 1, second is 12, third, 123 etc)

The first such numbers are $a_{36}$, $a_{44}$, $a_{144}$, $a_{152}$, $a_{216}$, ... So the lowest is $123\ldots343536$.
