So

57 36 +1 = 37 37 +2 = 39 39 +3 = 42 42 +4 = 46 46 +5 = 51 51 +6 = 57
42
The rule is 5 10 15 20 25 30 .... etc and accordingly the next number in the sequence will be 106
6 12 9 18 15 30 27 54 51
91
91
57 36 +1 = 37 37 +2 = 39 39 +3 = 42 42 +4 = 46 46 +5 = 51 51 +6 = 57
42
The rule is 5 10 15 20 25 30 .... etc and accordingly the next number in the sequence will be 106
the next prime number after 51 is 60 :)
46/9 = 51/9
158 One possible sequence is t(n) = 0.5*(19n2 - 7n + 40) for n = 1, 2, 3, ...
51
97
107 double difference each time 2 + 7 = 9 9 + 7 + 7 = 23 23 + 14 + 14 = 51 51 + 28 + 28 = 107
46/51 in lowest form = 46/51
