Answer:
Since this is a graph, I don't know how to help you sorry-
Its on your computer and I don't know how to put an answer down for you.
1/2 is written as a decimal as 0.50
An=a1+d(n-1)
a1=first term
d=common difference
n=which term
common difference is 5 first term is 2
an=5+2(n-1)
19th term is n=19
a19=5+2(19-1)
a19=5+2(18)
a19=5+36
a19=41
19th term is 41
