The series Goes as the Sum of Consecutive Prime Numbers Staring From 11.

11+13= 24

13+17=30

17+19=36

19+23=42

23+29=52

Therefore, 29+31 = 60

QED.

I hate this kind of problem because there are infinite possible solutions =/. I could find simple formulas to get 58, 62 and 64 as the next term. No more tries after that. But this solution was clever anyway! Gotta think of primes next time.
