Set A = { x,11,15,19, 23} *The numbers were randomly distributed in the set. Then find the value of x??

Statement 1: The numbers are in A.P
Statement 2: x is a prime number

• @Vivek......Read my statement carefully........Numbers in the Question were randomly arranged like: 19,23,x,11,15
  So, if we will use the 1st statement only, value of x can be 7 or 27
  But if we will use the 2nd statement along with the first statement, then out of 7 or 27, only 7 is a prime number....So, the required value of x= 7 only......
  
  Now tell guys, am I right??

• Only stmt 1 is sufficient to solve this problem...
  23-19=4, 19-15=4. 15-11=4, 11-x=4 ..since numbers are in AP..i.e X=7

• with statement 1 the common difference is 4
  according to rule of arithmetic progression the number is 7
  
  with statement 2 the prime number has difference 4 with 11 is 7
  
  so answer is
  either statement 1 or statement 2 is sufficient for to solve the problem

• Both Conditions are required. The value of x is 7.....
• 10 years agoHelpfull: Yes(7) No(11)
• If numbers are randomly distributed, then 2 conditions:
  a={11,15,,19,23,x} OR
  a={x,11,15,19,23}
  
  So both the conditions are required...

• only 1st condition required
  as it is in AP its format will be in a,a+d,a+2d ....
  here a+d=11
  a+2d=15
  from solving these both eqn d=4,a=7
  so x=7

• ans is 7.
  each number in a set was increased by 4.
  therefore
  x+4=11
  x=11-4
  x=7

• 7[difference is 4.due to they are in AP]
• 9 years agoHelpfull: Yes(0) No(0)
• ans is 7,since given numbers are in A.P the difference between two adjacent no must be constant
  
• 9 years agoHelpfull: Yes(0) No(0)
• Both the conditions are required
  
• 9 years agoHelpfull: Yes(0) No(1)
• only two possible ways to arrange these two numbers in a.p
  x,11,15,19,23 or 23,19,15,11,x
  
  from statement one we can say x=7(bcz d=4)
  from statement that can be 9,7,5,3,1
  so A is answr
