find multiples of 4 in [13, 125]. I solved it 125-13 = 112 / 4 = 28
but the correct equation is 124-16 = 108/4 = 27 + 1 = 28
I am trying to figure out why my method is incorrect. Thank you for any help. I
It’s fine
However, be careful with your method when one (or more) of your endpoints are multiples of 4.
