It appears that a number of -79 is missing in the sequence and so if you meant -58 -65 -72 -79 -86 then the nth term is -7n-51 which makes 6th term in the sequence -93

A single term, such as 51474339 does not define a sequence.
57 36 +1 = 37 37 +2 = 39 39 +3 = 42 42 +4 = 46 46 +5 = 51 51 +6 = 57
The given sequence is 11, 31, 51, 72 The nth term of this sequence can be expressed as an = 11 + (n - 1) × 20 Therefore, the nth term is 11 + (n - 1) × 20, where n is the position of the term in the sequence.
(Term)n = 59 - 2n
It appears that a number of -79 is missing in the sequence and so if you meant -58 -65 -72 -79 -86 then the nth term is -7n-51 which makes 6th term in the sequence -93
If by using the formula: nth term = n2+2 the sequence is 3 6 11 18 27 38 51 66.Then it follows that by using the same formula the sequence is III VI XI XVIII XXVII XXXVIII LI LXVI in Roman numerals.

46/51 in lowest form = 46/51
If you mean: 7 18 29 40 then the next term is 40+11 = 51
