The sequence in the question is NOT an arithmetic sequence. In an arithmetic sequence the difference between each term and its predecessor (the term immediately before) is a constant - including the sign. It is not enough for the difference between two successive terms (in any order) to remain constant. In the above sequence, the difference is -7 for the first two intervals and then changes to +7.
The 90th term of the arithmetic sequence is 461
The nth term is referring to any term in the arithmetic sequence. You would figure out the formula an = a1+(n-1)d-10where an is your y-value, a1 is your first term in a number sequence (your x-value), n is the term you're trying to find, and d is the amount you're increasing by.
In this case, 22 would have the value of 11.

It is an arithmetic sequence if you can establish that the difference between any term in the sequence and the one before it has a constant value.

The nth term of an arithmetic sequence = a + [(n - 1) X d]
An arithmetic sequence
A single term, such as 51474339 does not define a sequence.
The following formula generalizes this pattern and can be used to find ANY term in an arithmetic sequence. a'n = a'1+ (n-1)d.

Since there are no graphs following, the answer is none of them.
