Question

MEDAL !
The first four terms of a sequence are shown below.

6, 2, -2, -6

Which of the following functions best defines this sequence?

f(1) = 6, f(n + 1) = f(n) + 4; for n ≥ 1

f(1) = 6, f(n + 1) = f(n) - 2; for n ≥ 1

f(1) = 6, f(n + 1) = f(n) - 4; for n ≥ 1

f(1) = 6, f(n + 1) = f(n) + 2; for n ≥ 1

Answer 1

what I am getting is a = -2(2n-5) >.>

Answer 2

thats not an answer choice... wanna help me with something different if you can get the answer to this one

Answer 3

cant*

Answer 4

I am not very good in sequence & series :( but I tried

Answer 5

ok so how about

The average rate of change of f(x) between x = 11 to x = 21 is _____ml per °C and represents the rate of change of volume per degree rise in temperature.

Answer 6

lemme try

Answer 7

ok

Answer 8

Average rate of change Formula: m = y1-y2/x1-x2
95 - 105 / 11 - 21
-10 / -10

Answer 10

the answer is 1

Answer 11
