Below a sequence of number is given, fill the blank space
1) 6, 5, 43.2
2) 5, 4, 31.25
3) 4, 3, 21.33
4) 3, 2, .....

• 6^3=216/5=43.2
  5^3=125/4=31.25
  4^3=64/4=21.33
  So 3^3=27/2=13.5

• 6, 5, 43.20
  (6)^2 - (5)^2 = 11 and 43.20 - 11 = 32.20 and 32.20 - 31.25 = 0.95
  (5)^2 - (4)^2 = 9 and 31.25 - 9 = 22.25 and 22.25 - 21.33 = 0.92
  (4)^2 - (3)^2 = 7 and 21.33 - 7 = 14.33 and 14.33 - 0.89 = 13.44
  
  Since the difference is 0.95, 0.92....0.89
  
  Hence 13.44 is the answer according to series

• I think it shud be 13.44 as per the given series... what are the options
• 9 years agoHelpfull: Yes(12) No(6)
• i think answer will be 13.5.... options?

• Let the pattern be : a , b , c
  c = a * (a+1) + a/b
  
  43.2 : 6*7 + 6/5
  31.25 = 5*6 + 5/4
  21.33 = 4*5 + 4/3
  
  Ans is 13.5 ( 3*4 + 3/2)
  
• 9 years agoHelpfull: Yes(4) No(0)
• 43.2 - 31.25=11.95
  31.25 -21.33=9.92
  21.33 - ? =7.89
  ?=13.44
• 9 years agoHelpfull: Yes(2) No(1)
• 3/2=1.5 , take 0.5
  
  3*2+7=13
  hence, ans is 13.5

• 6*7(next Number)+6/5->42+1.2=43.2
  5*6+5/4->30+1.25=31.25
  4*5+4/3->20+1.33=21.33
  3*4+3/2->12+1.5=13.5
  So 13.5 may be the answer

• 6, 5, {(7*6)+(6/5)}=43.2
  5, 4, {(6*5)+(5/4)}=31.25
  4, 3, {(5*4)+(4/3)}=21.33
  3, 2, {(4*3)+(3/2)}=13.5 ....ans
• 8 years agoHelpfull: Yes(1) No(0)
• Ans : 3*2+(3+2)+(3/2)+(3-2)=13.5
• 8 years agoHelpfull: Yes(1) No(0)
• yes your answer is right
• 9 years agoHelpfull: Yes(0) No(2)
• 6*7=42. 6÷5=1.5
  42+1.5=43.5
  Same for remaining
• 9 years agoHelpfull: Yes(0) No(0)
• It is....
  (6*7+1)=43
  (5*6+1)=31
  (4*5+1)=21
  (3*4+1)=13....so 13 is the answer
• 8 years agoHelpfull: Yes(0) No(0)
• here option is not given so i think
  1st method:
  6^3=216
  216/5=43.2
  2=5^3=125
  125/4=31.25
  3 . 4^3=64
  64/3=21.33
  4. 3^3=27
  27/2= 13.5
