Step-by-step explanation:
40 divided by 5.49 will get you 7.28
72 divided by 9 will get you 8
Well, we know is centered at the origing, thus h,k are just 0,0.
using the provided vertex and focus point, gives us a distance for "a" of 9 and a distance for "c" of 15, check the picture below.

I am not sure sorry about that
Help me, help you.
Oh, what you gonna do?
Cuz' I don't got a clue.
No, I ain't no Scooby-doo!
Help me, help you!
Okay, what's up?
The common difference equals:
10 (as 14-4=10, 24-14=10…)
The explicit formula of this sequence is:
Because Tn=4+(n-1)•10
T1=4+(1-1)•10=4
T2=4+(2-1)•10=14
.
.
.
Therefore T8=4+(8-1)•10=74
So the answer is the second option:)
