Answer 1

Answer

.

$f(100) = 498$

.

Explain

.

$f(2) = 8$

$f(3) = 13$

.

Find b

$3b - 2b = 13 - 8$

$b = 5$

.

Find f(1)

$f(1) = f(2) - b$

$f(1) = 8 - 5$

$f(1) = 3$

.

Find f(100)

$f (x)= f(1) + (x - 1)b$

$f(100) = 3 + (100 - 1)5$

$f(100) = 3 + (99)5$

$f(100) = 3 + 495$

$f(100) = 498$
