You are going to have to learn something about f(2)
Step One
f(1) = 160
f(1 + 1) = - 2f(1)
f(2) = -2 * 160
f(2) = -320
Step Two
The easiest way is just to keep on going. This is recursive which means you use the last answer to get the next one.
f(3) = -2f(2)
f(3) = -2 * -320
f(3) = 640 Two minus' make a plus.
Step Three
Find f(4)
f(4) = - 2 f(3)
f(4) = -2 * 640
f(4) = - 1280 <<<<<<<<< answer
Alternate Method
f(n) = 160 * (-2) ^ (n - 1)
f(4) = 160 * (-2)^(4 - 1)
f(4) = 160 * (-2)^3
f(4) = 160 * (- 8)
f(4) = -1280
Step-by-step explanation:
To find each term, take the value of k (the term number) and multiply it by the square of the previous term.
Answer:
c. mean: 9/20, median: 2/5, mode: 3/4
Step-by-step explanation:
3/4
,
2/5
,
1/10
,
3/4
,
1/4
It is best to order this list from low to high
low end, 1/10, 1/4, 2/5, 3/4, 3/4
middle is 2/5
mode = 3/4 the most repeated
mean: [2/20 + 5/20 + 8/20 + 15/20 + 15/20] * (1/5)= 45/20 *(1/5)
