Is the sequence geometric? 48, 46, 44, 42, ... A. yes B. no I said yes because when you divide like so: 42/44 = .9545454545 etc 44/46 = .956521 etc and etc But is the answer yes even though only the first 2 numbers after the decimal are the same throughout?

    Geometric means that from one element to the next you keep dividing by the same number.

    Here you are subtracting 2 from the current element to get to the next one.

    It is not geometric. If it were your test would have given you exactly the same number.
