Q. What is the next number of the following sequnces

1. 4,3,6,5,11,10,19,18,30,29,?

2. 3,4.5,7,4,6,8.5,7.5,10,6,?

3. -12,6,-15,-5,18,-14,9,3,-18,?

4. 4.2,26.0,8.9,8.4,52.0,17.8,16.8,104.0,?

5. 1370,1320,1070,-180,?

6. 0.5,2,3,4.5,6.75,?

7. 18,6,24,4,30,10,12,2,6,?

8. 1,1,3,9,11,121,?

9. 48,24,35,7,16,8,75,15,80,?

10. 1.8,3,0.6,2.5,5,0.5,3.4,2,1.7,4.8,6?

11. 30.5,31,30,0,67.2,67,70,100,183.9,?

• 1> 4-1=3 and 3+3=6
  6-1=5 and 5+6=11
  11-1=10 and 10+9=19
  19-1=18 and 18+12=30
  30-1=29 and 29+15=44
  so the next no in series is 44

• 5) 1370-1320=50
  1320-1070=250=(50*5)
  1070-(-180)=1250=(250*5)
  -180-(-6430)=6250=(1250*5)
  
  so,ans=-6430

• Explaination of answers:
  4) (4.2,26.0,8.9),(8.4,52.0,17.8),(16.8,104.0,...)
  4.2*2=8.4
  26.0*2=52.0
  8.9*2=17.8
  Then,
  8.4*2=16.8
  52.0*2=104.0
  17.8*2=35.6
• 10 years agoHelpfull: Yes(8) No(1)
• Ans no.8:
  there is series of square and then plus 2.
  1 =1
  1^2=1
  1+2=3
  3^2=9
  9+2=11
  11^2=121
  121+2=123
  So the ans is 123....

• Explanation of answer:
  9) (48,24),(35,7),(16,8),(75,15),(80,...) answer : 40
  48/2=24
  35/5=7
  16/2=8

• Explanation of answer :
  10) (1.8,3,0.6),(2.5,5,0.5),(3.4,2,1.7),(4.8,6,...) answer : 0.8
  pattern is like (a,b,c) : a/b=c
  1.8/3=0.6
  2.5/5=0.5
  3.4/2=1.7
  similarly,
  4.8/6=0.8

• ans for qus1:
  4-3=1,6-3=3(i.e.3*1=3)
  6-5=1,11-5=6(i.e.3*2=6)
  11-10=1,19-10=9(i.e.3*3=9)
  19-18=1,30-18=12(i.e.3*4=12)
  30-29=1, by seeing this series it is conform that next multiple of 3 is (3*5=15)
  so the next no must be 29+15=44.
  
  so the ans:44

• Explanation of answers:
  5)1370,1320,1070,-180,...
  1370-50=1320
  1320-(50*5)=1070
  1070-(50*5*5)=-180
  -180-(50*5*5*5)=-6430

• Question 2) Answer 9
  Explanation
  ------------------------------------------------------------------------------------------
  3,4,5,6 is a separate series (which has no relation with the answer anyway)
  set 1------> (4.5,7) diff. is 2.5 --> Decimal followed by Number
  set 2------>(6,8.5) diff. is 2.5 --> Number followed by Decimal
  set 3------>(7.5,10) diff. is 2.5 --> Decimal followed by Number
  set 4------>(?,?) --> Number followed by Decimal(Obviously)
  
  If you look carefully,
  
  adding 1 to the Number in set 1(7) gives the Whole part of Decimal in set 2(8 in 8.5)
  adding 1 to the Number in set 2(6) gives the Whole part of Decimal in set 3(7 in 7.5)
  adding 1 to the Number in set 3(10) gives the Whole part of Decimal in set 2(11 in 11.5)
  so if you have to get 11.5 as Decimal in set 4 the Number should be 9
  
  Finally set 4------>(9,11.5)
  ------------------------------------------------------------------------------------------
  Hence 9 is the answer

  ans 9: 24*2=48, 7*5=35, 8*2=16, 15*5=75, n the ans is: 40*2=80.. 40 is the ans
• 10 years agoHelpfull: Yes(1) No(0)
• 8Q ans: 1,1,3,9,11,121 = 1,1^2,3,3^2,11,11^2.
  
  1,3,11 sequence difference are 2,8 = 2,2^3.
  so next will 8^3 = 512
  so the ans is : 512+11 = 523

  (30.5, 31), (30,0) , (67.2 , 67), (70, 100), (189.9 , ?)
  
  (30.5, 31) >> increased by 0.5
  (30,0) >> increased by 30
  (67.2 , 67) >> decreased by 0.2
  (70, 100) >> increased by 30
  (189.9 , ?) >> from the first and the third couples we can see that -0.7 is the number what the followings.
  
  means: first +0.5
  third - 0.2
  difference between them -0.7
  so, fifth couple : difference second and -0.7 is -0.9
  
  ans= 189.9- 0.9 = 183
