Determine the average rate of change
Average rate is calculated as thus;
<em>In this case; b = 12 and a = 6</em>
Calculating f(12)
Calculating f(6)
Substitute 12 for b and 6 for a in
Substitute values for f(6) and f(12)
A = 6
tn = a + (n - 1)d
t4 = 6 + 3d = 12
3d = 12 - 6 = 6
d = 6/3 = 2
f(n + 1) = f(n) + 2
