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) is 31

Solution:

Given that the sequence is defined by formula:

To find: f( 1 )

Also given that,

So, we can say,

Substitute n = 3 in given formula

Now we got, f(3) = 25

Use the similar steps to find for f(2)

Substitute n = 2 in given function

Use the similar steps to find for f(1)

Substitute n = 1 in given function

Thus value of f(1) is 31

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4

zero

step-by-step explanation:

f(2)= x-2

plug in the 2 in the "x"

f(2)=2-2

f(2)=0
