  Solution: if we divide the series in 2 digit group then:
  1st group : (7,4)= 7-4=3
  2nd group :(6,3)= 6-3=3
  So the next term is 4.5-3=1.5
  answer is 1.5
  5.) 2,6,5,14,11,26,17
  Solution: Prime numbers are 2,3,5,7,11,13,17,19
  2,(3*2),5,(7*2),11,(13*2),17,(19*2)
  answer is 38
  6.)3,4,12,76,588
  Solution: The difference between consecutive terms are
  4-3=1 which can be written as 2^0=1
  12-4=8 which can be written as 2^3=8
  76-12=64 which is 2^6=64
  588-76=512 which is 2^9=512
  So the next term would be 2^12+588=4096+588=4684
  answer is 4684
  7.) -3,6,1,-2,4,-1,-1,2,-3
  Solution: -3*-2=6 = 6-5=1,
  -2*-2=4 =4-5= -1,
  -1*-2=2 =2-5= -3
  -0*-2=0
  Answer is 0
  8.) 4,11,66,74,370
  Solution: 11-4=7
  11*6= 66
  74-66=8
  74*5=370 which means the next term will be increased by 1 i.e 370+9 = 379
  Answer is 379
  9.)1/2,1/2,1/4,1/6,1/8,1/18,...........
  Solution: Take the alternate series
  1st series is : 1/2,1/2^2,1/2^3,1/2^4...
  2nd series: 1/2,1/2*3,1/6*3,1/18*3...
  Answer is 1/16
  10.)12,22,35,68,15,28,31
  Solution: if we pair 2 number as a group then
  12-1=11 11*2=22,
  35-1=34 34*2=68,
  15-1=14 14*2=28,
  31-1=30 30*2=60
  Answer is 60

• 10.)12,22,35,68,15,28,31
  Solution: First we take 12 the subtract that with 1 we get next number and repeat it for others
  12-1=11 11*2=22,
  35-1=34 34*2=68,
  15-1=14 14*2=28,
  31-1=30 30*2=60
  Answer is 60
