In a between-subjects 2x2 factorial design with 200 total participants, how many participants should be randomly assigned to each factorial combination

I’m vary good with science if you need with that

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?
