subtract like terms
5a^3 - 6a^3 = -a^3
7 - 4 = 3
answer is -a^3 + 2a^2 - 4a + 3
4. I think 4 is 128
16x16=256 and divide that by 2 and its 128
Mark me Brainly answer 2/5
Well, since we know is a geometric sequence, we can always get the common ratio of it by simply dividing one value by the one behind it... so let's do so, with say hmm -32 and 8 -32/8 = -4 <-- our common ratio
the first term is -2
