Q. What is the next number of the following sequence.
1,1/2,3/2,2,5,1/3,16/3,15,12,1/4,49/4,7,...

• 1-(1/2-3/2)*1=2
  5-(1/3-16/3)*2=15
  12-(1/4-49/4)*3=48
  so 7 should be replaced by 48

• 1+1/2=3/2
  2+3=5 and 5+1/3=16/3
  15-3=12 and 12+1/4=49/4
  so 7+3=10

• 148/4
  1,1/2,3/2,2,5,1/3,16/3,15,12,1/4,49/4,7 cam be written as
  1,0.5,1.5,2,5,0.33,5.33,15,12,0.25,12.5,7
  we could see the pattern
  as 1 3 5 3 5 now next should be 5
  so the last no will be 37.5
  which can be written as 148/4 hence the ans

• 49/4+7=77/4
• 11 years agoHelpfull: Yes(1) No(3)
• 1-(1/2-3/2)*1=2;
  5-(1/3-16/3)*2=15;
  12-(1/4-49/4)*3=48;
  so 7 should be followed by 48
