calculate the value {(n+1)th term - nth term}
The reslt will readily produce.
If we calculate {(n+1)th term - nth term}, we will get :
2,3,5,7: all are consecutive primes starting from 2.
So,evidently, the next term in the above will be the next prime in the seq,i.e, = 11
So, the answer will be 22+(11) =33.

15+7=22
22+11=33
prime nos. are being added to each no... - 12 years agoHelpfull: Yes(0) No(4)
- there is a difference involving consecutive prime numbers..so the next prime number that has to be added is 11..answer is 33
- 12 years agoHelpfull: Yes(0) No(0)
- the next number is 31
- 5 years agoHelpfull: Yes(0) No(0)
- the difference between each digit is a prime number like
7-5=2
10-7=3
15-10=5
22-15=7
so
next is 11
X-22=11
so x=33 - 4 years agoHelpfull: Yes(0) No(0)
