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 fin) 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
fin) = 0.6n + 2.5
f(n + 1) = f(n) +1.9
O fin + 1) = f(n)-0.6
