If you fit a linear equation, Un = 24 - 11n then the 6th term is 42.

However,

Vn = (-29x4 + 290x3 - 1015x2 + 790x + 744)/60 gives the sequence 13, 2, -9, -20, -42.6, and -100

Wn = (7x4 - 70x3 + 245x2 - 570x + 648)/20 gives the sequence 13, 2, -9, -20, -22.6, and 0

while

Xn = (71x4 - 710x3 + 2485x2 - 4210x + 3144)/60 gives the sequence 13, 2, -9, -20, -2.6, and 100

By suitable choice of polynomial, any number at all can be in sixth place.

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.

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 following formula generalizes this pattern and can be used to find ANY term in an arithmetic sequence. a'n = a'1+ (n-1)d.

The nth term of an arithmetic sequence = a + [(n - 1) X d]

A single term, such as 51474339 does not define a sequence.

An arithmetic sequence

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.

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