find the next number in the sequence

5,7,10,15,22,-

• 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,
  5+2,7+3,10+5,22+11,
  2,3,5,7,11
  all these are prime numbers.
  so the nexr prime number after 7 is 11.

• 5+2=7
  7+3=10
  10+5=15
  15+7=22
  22+11=33
  prime nos. are being added to each no...

• there is a difference involving consecutive prime numbers..so the next prime number that has to be added is 11..answer is 33

• the next number is 31
• 6 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
