complete the series 5, 7, 10, 15, 22..

5,7,10,15,22,?

observe the number series and we can find 
7-5=2
10-7=3
15-10=5
22-15=7 

The difference between the adjacent numbers itself form a series of consecutive prime numbers 2,3,5,7 and the next will be the prime number 11 and adding 11 to 22 we get the next number in the series as 33

series is 5,7,10,15,22,33.

HOPE IT MAY HELP YOU

in the given series we see that every time we add a prime number to get the next number in the series. we first added 2 then 3 then 5 and then 7.now the next prime number is 11 and the previous number in the series is 22 so we will get the next number in the series by adding 11 to 22 and so we get 33 as the next number of the series. likewise if we proceed the next numbers will be 46,63 and so on
HOPE THIS HELPS!!!! :)
