Sorry everyone, it has been a long time since my last post here.

So, it is the sum of two sexy primes (http://www.mathisfunforum.com/viewtopic.php?id=19312) and square numbers, and subtracted by the square root.

SP = Sexy prime

SQN = Square number

SQRT = Square root

Example :

(SP + SP) + (SQN + SQN) - (SQRT + SQRT)

(5 + 11) + (1 + 4) - (1 + 2)

(16 + 5) - 3

21 - 3

18

Go, continue the sequence!

(17+23) + (9 + 16)-(3+4) = 58
