No it doesn’t because 16+16=32, +50 cents = 32.50

Answer:

Recursive Formula:
a{n}=an-1+14; a1=16.50

Explicit Formula: an=2.5+14n

Explanation:

The common difference is 14, as you would add 14 to 16.50 and get 30.50 for two tickets. However; the tickets are not the same amount of money each, since 16.50 is not a multiple of 14, (neither are 30.50, 44.50, and 58.50.)

I took the quiz and got it 100% Correct.
