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
9-2=7, 23-9=14, 51-23=28, 107-51=56. therefore, since the next number in the sequence will be twice the previous difference, it will be 107+112 which is 219

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, ...

46/51 in lowest form = 46/51
107 double difference each time 2 + 7 = 9 9 + 7 + 7 = 23 23 + 14 + 14 = 51 51 + 28 + 28 = 107
