Answer: F
Explanation:
You can figure this out by plugging in the values of n for each expression and seeing which one gives you the given sequence.
Starting off with F
A(n) = 14.5 + 1.5(n-1)
A(1) = 14.5 + 1.5(1-1) --> 14.5 + 1.5(0) = 14.5
A(2) = 14.5 + 1.5(2-1) --> 14.5 + 1.5(1) = 16
A(3) = 14.5 + 1.5(3-1) --> 14.5 + 1.5(2) = 17.5
You can put in the remaining values of n if you want, but you should be able to notice that A(n) increases by 1.5 each term which follows the given sequence.
while J looks similar, it starts its sequence at 16 instead of 14.5 as it doesnt subtract 1 from n.
