Question

F(n) = 93 + 4(n − 1)

Answer 1

Answer:

$f(1) = 93$, $f(n) = f(n-1) +4$

Step-by-step explanation:

The value of f(1) is:

$f(1) = 93 +4\cdot (1-1)$

$f(1) = 93$

The values for n and n-1, are respectively:

$f(n-1) = 93 + 4\cdot (n-2)$

$f(n) = 93 + 4\cdot (n-1)$

After some algebraic manipulation, the following expression is obtained:

$f(n) = 93 + 4\cdot (n-2) + 4$

$f(n) = f(n-1) +4$
