10,14,17,19,x
Find x

• 10,14,17,19,x
  
  
  14 - 4 = 10
  17 - 3 = 14
  19 - 2 = 17
  
  difference of numbers is reducing by 1.
  Hence next number is 19 + 1 = 20
  
  so x=20

• x=20..since difference is continuosly decreasing as 4,3,2.....so the next number after 19 is 19+1=20.
• 13 years agoHelpfull: Yes(2) No(4)
• Ans:20
  10+4=14
  14+3=17
  17+2=19
  19+1=20
• 13 years agoHelpfull: Yes(1) No(2)
• Ans. 20
  
  Because the difference between two no decrease with -1.
  Like differece between 10 & 14 =4
  ...................14 & 17 =3
  ...................17 & 19 =2
  ...................19 & 20 =1

• Answer is 20. The difference between the numbers is 4, 3, 2..next no is 19+1=20.

• 20
  it is in descending order from 4,3,2,1
• 13 years agoHelpfull: Yes(0) No(4)
• 1) 10
  2) 10 + 4 = 14
  3) 14 + 3 = 17
  4) 17 + 2 = 19
  5) 19 + 1 = 20 = X ....... ANS

• Dipin, These are the sums of pairs of composite no.s from 4
  10=4+6,
  14=6+8
  17=8+9
  19=9+10
  in the same way,
  x=10+12=22

• answer is 20
• 13 years agoHelpfull: Yes(0) No(0)
• Ans:20
  10+4=14
  14+3=17
  17+2=19
  19+1=20

• 10,14,17,19,20
  series differences is +4,+3,+2
  so next is +1 means 19+1=20
• 13 years agoHelpfull: Yes(0) No(0)
• 20
  Expln: The series is like
  10 = 10
  10 +4 = 14
  14 +3 = 17
  17 +2 = 19
  19 +1 = 20
