• Hey guys...take
  There are two types of AP..increasing and decreasing...if you will consider increasing AP then series will be 3, 8, 13,18,23,28,33
  So x will be 33..but if you consider decreasing AP then series will be 28,23,18,13,8,3. So x will be 3. So from 1st statement we cannt conclude..2nd statement is that x should be prime..so 33 will be eliminated..so x will be 3 only...so i think both statements are required

• This Question is not asking you about the value of x.
  
  Instead you have have to answer as
  Mark a if the question can be answered by using one of the statements alone, but cannot be answered by using the other statement alone.
  
  Mark b if the question can be answered by using either statement alone.
  
  Mark c if the question can be answered by using both statements together, but cannot be answered by using either statement alone.
  
  Mark d if the question cannot be answered enen by using both the statements together.
