Asequence is defined by the recursive function f(n + 1) = –10f(n).

if f(1) = 1, what is f(3)?

3
–30
100
–1,000

100

Step-by-step explanation:

f(n+1) = -10f(n)

f(1) = 1

f(2) = -10f(1) => f(2) = -10·1 => f(2) = -10

f(3) = -10f(2) => f(3) = -10·(-10) => f(3) = 100

step-by-step explanation:

20% of 120 is 24. if you subtract 24 from 120 you get 96

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)
