Find the fifth term in the sequence that is defined as follows: an=2(-1)^n​

What term makes it inconsistent y=2x - 4

I'm confused on this could anyone me and show me what i need to do to solve it.

Acolony contains 1500 bacteria. the population increases at a rate of 115% each hour. if x represents the number of hours elapsed, which function represents the scenario? f(x) = 1500(1.15)" f(x) = 1500(115) f(x) = 1500(2.15) f(x) = 1500(215)
