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

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
