Asequence is defined by the formula f(n + 1) = f(n) – 3. if f(4) = 22, what is f(1)?

The value of f(1)=31

Step-by-step explanation:

Given:

f(4)=22

We need to find the f(1)

Put n=3 into recursion formula

Put n=2 into recursion formula

Put n=1 into recursion formula

Hence, The value of f(1)=31

she played for 18.75 hours.

step-by-step explanation:

if she played 2/4 of a hour on tuesday. and there is 60 minutes in an hour and 60 divided by 4 is 7.5. and she played 2/4 of an hour on thursday then again 60 divided by 4 is 7.5, you add 7.5+7.5=56.25. now you have to do 1/4 of an hour, it equals 3.75. now you have to add them all up. 3.75+7.5+7.5=18.75
