F(1)=-8
f(n)=f(n-1)-3
Find the explicit formula

f(1) = -8, simply is a way of saying, the 1st value in the arithmetic sequence is -8.

f(n) = f(n-1) - 3, is another way of saying, following values are just, the previous minus -3.

so in short, -3 is the common difference, since that is what we're "adding" to get the new value in the sequence.

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
