158 One possible sequence is t(n) = 0.5*(19n2 - 7n + 40) for n = 1, 2, 3, ...
51 is not a prime number: 3x17=51
51 is composite number
23 is the prime number.
No, according to algebra there is no real answer. But if you take the numbers 35, 45, 50 and 51, it would be 51.125(The number that increases itsself divides by 3 everytime)
31
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
91

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 :)

Start by adding 7, then add 7x2, then 7x4, then 7x8, etc. 2 + (7x1) = 9 9 + (7x2) = 23 23 + (7x4) = 51 51 + (7x8) = 107 The next number is 219.
The number halfway between two values is the average of those values. In this case, the average of 23 and 51 is (23 + 51) / 2 = 74 / 2 = 37. Therefore, the number halfway between 23 and 51 is 37.
51 is composite number
