    It's 64, the sequence is described by the formula:



    is undisputedly 64.

    I don't see any way for the answer to be 36 without some contorted logic. But with only the first 3 terms given, it may well be possible to make some kind of argument for it being 36.

    However the sequence I've highlighted here is the obvious answer.
