• 1. ans 14
  the difference between consequent numbers is +3 +4 -8 then +4 +5 -7 then +5 +6 -6
  so 8+6=14

• 2)series break in 2 part
  9,26/3,25/3,8,(diff=1/3)
  15,29/3,27/2...
  next term is 8-1/3=23/3 ans
  
  3)series break in 2 part and see 1 series
  11,17(6),23(6),31,(8),so next term 39(8)...
  ans=39
  
  8)in series
  9,12(9+3),4(12/3),8(4+4),12(8+4),15(12+3),5(15/3),9(5+4),3(/3),6(+3),2(/3),6(+4)
  9(+3) so next term is 9/3=3 ans...
  9)series break in 2 parts
  (1/7,4/9,7/11,10/13,13/15....)and (3/4,5/6,7/8,9/10...)
  so ans is=10/13...
  
  10)8/.5=16
  15/.3=50
  6/,2=30
  4,4.5,5,5.5 implement b/w these 3 number pair so ans is 5

• 4) Divide the series into 3parts:
  i) 1+3+1+2.5 = 7.5
  ii) 5+1+4+5 = 15
  so we can see sum of i*2=ii
  therefore,
  sum of ii*2=sum of iii
  iii) 4+8+7+(11)= 30 that satisfies the above equation.
  Ans. : 11.

• 3)this series is divided in 2 parts, 1st part is
  11-3=8
  11+6=17
  17-3=14
  17+6=23
  then second part of series starts where
  23+1=24
  23+8=31
  31+1=32
  31+8=39(ANSWER)

• 6) add 0 with 7
  add 12 with multiple of 7(2*7) i.e 14
  add 23 with next multiple of 7(3*7) i.e 21
  (0,8) 0 + 7 = 8
  (12,26) 12 + 14 = 26
  (23,x) 23 + 21 = 44

• solution is 1/6
  (5/6, 1/3, 1/2)=> 5/6 = 1/3 + 1/2
  (1/2, 2/8, 1/4)=> 1/2 = 2/8 + 1/4
  (5/6, 1/6, 2/3)=> 5/6 = 1/6 + 2/3
  so
  1/2, 1/3, ? gives
  1/2= 1/3+x
  x=1/6

• 2+(3)=5
  5+(4)=9
  9(-8)=1
  1+(4)=5
  5+(5)=10
  10(-7)=3
  3+(5)=8
  8+(6)=14 so ans=14
  that is +4 -8 +4 then +5 -7 +5 so next will be +6 -6 +6
