Heya! This can be represented as a geometric number pattern. This is a number pattern which has a constant multiplier (in this case it doubles so the multiplier/ratio is 2). I’ve outlined a general formula for geometric/exponential number patterns where a is the first term, r is the ratio, and n is the term number. In this case, n is the amount of months the rabbits have been doubling for. The answer will be the y equation, where x is a positive natural number (i.e 1,2,3 etc. because we don’t have half months)
