I hope this helps!

37-12=25 5 rows of 5

37-1=36 6 rows of 6

from the first data:

it has to be a multiple of 5 + 12, could be

17 22 27 32 37 42 47 ...

from the 2nd data:

it has to be a multiple of 6 + 1 , could be

7 13 19 25 31 37 43 ..

ahhh, 37 is found in both , which is also Lila's answer.

There were 37 choir members
