• 1.25+0.25=1.50+0.25=1.75
  3-2=1-2=-1
  7.1+1=8.1+1=answer is 9.1

• ans=9.1
  in that series +.5,-2,+1 added as so that no. would be 3rd no.right to that no.
  1.25+.5=1.50
  3-2=1
  7.1+1=8.1
  1.50+.25=1.75
  1-2=-1
  8.1+1=9.1

• +0.25,-2,+1 is added and this continues...so ans is 9.1
  1.25+0.25=1.5
  3-2=1
  7.1+1=8.1
  1.5+0.25=1.75
  1-2=-1
  8.1+1=9.1(ans)

• it is a triplet series. i.e. 1.25,1.5,1.75 and 3,1,-1 and 7.1,8.1,9.1
  so ans is 9.1

• 1.25,1.50,1.75-----1st series
  1.25+0.25 = 1.50
  1.50+0.25 = 1.75
  3,1,-1-----------------2nd series
  3-2 = 1
  1-2 = -1
  7.1,8.1,?--------------3rd series
  find the third one
  7.1+1.0 = 8.1
  8.1+1.0 = 9.1(ans)

• Three series continuing at a time
  1.25+ 0.25 = 1.50 + 0.25 = 1.75
  3 - 2 = 1 - 2 = -1
  7.1 + 1 = 8.1 + 1 = 9.1 (ans)
• 9 years agoHelpfull: Yes(0) No(0)
• 1st pattern= add 0.25 in each term(1.25, 1.5, 1.75,.....)
  2nd pattern= subtract -2 in each term(3,1,-1,....)
  3rd pattern= add 1 in each term(7.1, 8.1, ***,.....)
  So ans is 9.1
