What is the next number of the following sequence

1)5 6 3 78 3 9 10

2)6 12 6 13 7 12 7 13 8

3)16 21 25 28

4)20 25 26 22 29 30 24

5) 13 17 29 14 18 28 15 19

• 1) 3 is insert after every 2 term
  series 5,6,7,8,9,10
  after insert 3
  5,6,3,7,8,3,9,10,3,11,12.......
  so ans is 3
  
  2) series is (6 12 6)13(7 12 7)13 (8 12 8)
  so next term is 12
  
  3)difference is decrease
  16+5=21
  21+4=25
  25+3=28
  28+2=30
  so next term is 30
  
  4) break IN 3 SERIES
  20,22,24,26
  25,29,33,37
  26,30,34,38
  COMBINE ALL
  20 25 26 22 29 30 24 33 34.....
  ANS -33
  
  5)13,14,15,16,17,18...

• 1. Combine the consecutive 3 nos as following -
  (5,6,3) (7,8,3) (9,10,x)
  observe that 3 comes after every two nos in each group.
  so, the value of x is 3.
  
  2. Combine 2 nos in a group as -
  (6,12), (6,13), (7,12), (7,13) , (8,x)
  Observe that , first no of each group is repeating two times .
  second no of each group increments by 1 in alternate group and then it comes to its own value .
  eg - case of first no of each group
  6,6,7,7,8
  case of second no of each group
  12,13,12,13,x
  so, the value of x will be 12 as 12 is increases by 1 in next group and then it comes to its own value in the coming group.
  
  3. 16,21,25,28,x
  calculate the difference between two consecutive no, you will get -
  5,4,3
  you are observing that the value (5,4,3) is decreasing by 1 , then the next decreased value is 2.
  now add the value of 2 in 28, you will get 30.
  the ans will be 30.
  
  4. 20,25,26,22,29,30,24
  Combine the three consecutive number in a group as following -
  (20,25,26), (22,29,30),(24,x)
  in every group the first no is incremented by 2.
  in every group the second no is incremented by 4.
  so, the second number of each group is
  (25,29,33).
  so, the answer is 33.
  
  5. 13,17,29,14,18,28,15,19
  combine every 3 consecutive no in a group as -
  (13,17,29) , (14,18,28) , (15,19,x)
  observe , 3rd no of each group is decreasing by 1 -
  29-1=28
  28-1=27
  so, the answer is 27.

• 1) 2*5*6+6*3=78 so 2*3*9+9*10=144
  2)12
  3)30
  4)33,34
  5)27 as 13+1=14,17+1=18,29-1=28 so 14+1=15 18+1=19 and 28-1=27

• 1)3
  because 3 is repeated every times after 2 digits
  2)12
  3)30
  because 16+5=21
  21+4=25
  25+3=28
  28+2=30
