3n - 1
When n = 1,
3n - 1 = 3*1 - 1 = 3 -1 = 2
When n = 2,
3n - 1 = 3*2 - 1 = 6 -1 = 5
When n = 3,
3n - 1 = 3*3 - 1 = 9 -1 = 8
Hence, the first three terms are 2, 5 and 8.
Apparently, we are to presume the cost of the pizza is proportional to its area. The ratio of areas is proportional to the square of the ratio of diameters. Hence we expect a 20" pizza to cost
