A sequence is defined by the recursive formula f(n+1)=f(n)-2. If f(1)=18, what is f(5)?

N76 [4]

Answer:

$f(5)=10$

Step-by-step explanation:

A sequence is defined by the recursive formula $f(n+1)=f(n)-2$

If $f(1)=18,$ then

for $n=1: f(2)=f(1+1)=f(1)-2=18-2=16$

for $n=2: f(3)=f(2+1)=f(2)-2=16-2=14$

for $n=3: f(4)=f(3+1)=f(3)-2=14-2=12$

for $n=4: f(5)=f(4+1)=f(4)-2=12-2=10$

Molodets [167]

Answer:

N'(9, -1)

Step-by-step explanation:

N(-5, -1)

Point N has x-coordinate -5. It is 5 units to the left of the the y-axis, and another 2 units away from the line x = 2. That makes point N 7 units to the left of the line x = 2. 7 units to the right of line x = 2, the x-coordinate is 2 + 7 = 9.
