represent the arithmetic series using the recursive formula.

94, 87, 80, 73, …

a] f(n) = f(1) + (7)
b] f(n) = f(1) + (−7)
c] f(n) = f(n − 1) + (7)
d] f(n) = f(n − 1) + (−7)

D] f(n) = f(n − 1) + (−7)

Step-by-step explanation:

since you already know is an arithmetic series, you have to find the common difference.

87 - 94 = -7

80 - 87 = -7

73 - 80 = -7

the formula for the nth term is f(n) = f(n-1) + d

where f(n-1) is the previous term and d is the common difference, so if youu substitute you get:

f(n) = f(n-1) + d

f(n) = f(n-1) + (-7)

D

Step-by-step explanation:

f(n) - f(n-1) = 87 - 94

f(n) - f(n-1) = -7

f(n) = f(n-1) - 7

i used to know how to do this in 7th but i forget easily

step-by-step explanation:

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )
