Question

This sequence represents the diameters of circles used to create an art project:

2.5 cm, 3.1 cm, 3.7 cm, 4.3 cm
Let f(n) represent diameter in centimeters and n the term number in the sequence. Which equation represents the sequence of diameters?

f(n) = 0.6n + 1.9
f(n) = 0.6n + 2.5
f(n + 1) = f(n) + 1.9
f(n + 1) = f(n) – 0.6
