If f

f(1)=10 and
f

f

−
n
f(n)=−5f(n−1)−n then find the value of
f
(
5
)
f(5)

f(1)=10

f(n)=nf(n-1)+5

f(2)=2f(1)+5=2*10+5=25

f(3)=3f(2)+5=3*25+5=75+5=80

f(4)=4f(3)+5=4*80+5=320+5=325

f(5)=5f(4)+5=5*325+5=1625+5=1630

step-by-step explanation:

company a

step-by-step explanation:

using the linear regression models , it is found that company a   pays about $14 more. but using the same regression (linear) company b pays about $10 more.
