List of primes = 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97 ...

2 + (2nd prime which is just greater than 2)3 = 5

5 + (4th prime which is just greater than 5)7 = 12

12 + (6th prime which is just greater than 12)13 = 25

25 + (10th prime which is just greater than 25)29 = 54

54 + (17th prime which is just greater than 54)59 =113

113 + (31st prime which is just greater than 113)127 = 240

240 + (53rd prime which is just greater than 240)241 = 481

481 + (94th prime which is just greater than 481)487 = **968.**
