3
5+1=6
7
11+1=12
13
17+1=18

- 10 years agoHelpfull: Yes(6) No(5)
- If I consider that the series is a mixed series of two series :
6,12,18,24,_ (sequence of multiples of 6)
and
3,7,13,19,_,_ (sequence of prime nos. skipping one of the in between, i.e., 3,[5],7,[11],13,[17],19)
according to this, the first missing term will be 29 i.e., 19,[23],29
the second missing term will be a multiple of 6 i.e., 30
the third missing term will be 37 i.e., 29,[31],37
hence the complete series is :
3,6,7,12,13,18,19,24,29,30,37 - 6 years agoHelpfull: Yes(1) No(0)
- They are considering consecutive prime numbers.
29 should be the answer. if 29 is missing, then the ans is 32 - 10 years agoHelpfull: Yes(0) No(0)
- i think next will be 29 then next 30
- 6 years agoHelpfull: Yes(0) No(0)
