Given the formula for an arithmetic sequence f(7) = f(6) + 4 written using a recursive formula, write the sequence using an arithmetic formula

of(7) = f(1) + 24

1(7) = f(1) + 20

of(7) = f(1) + 12

of(7) = f(1) + 4

f(7) = f(1) + 24

Step-by-step explanation:

Arithmetic explicit formula has the form:

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

Arithmetic recursive formula has the form:

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

Given the expression: f(7) = f(6) + 4, it can be seen it's expressed in the recursive form with n = 7, n-1 = 6 and d = 4. Using these values in the explicit formula we get:

f(7) = f(1) + 6*4

f(7) = f(1) + 24

a)(x-2)^2+(y-1)^2=9
