It is very easy..
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.

Thanks to All..:-):-) ..

33 is the answer
sequence is
5,7,10,15,22,33
the difference between the numbers are,

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
