Question

100, 96, 104, 88, 120, 56, ? what comes next (184, 140, 77, 124, 128?) choices

Answer 1

think about it like this, first you are subtracting four, then adding eight, then subtracting 16, then adding 32, then subtracting 64, so we need an equation that will give those values. luckily we can notice that these all seem to be powers of two, and that they seem to be alternating. this gives us a clue that the number we are using is being raised to an exponent, and that it is negative (hence the -,+,-,+)

Answer 2

184 because
100 96 104 88 120 56 184
-4 +8 -16 +32 -64 +128

Answer 3

looking at it we can guess that it may look something like this:

(-2)^2+i

where i is your iteration. so just multiply the last thing the function did by -2 and add it to the result to see what you get!
