What is the next number of the following sequence
.7, 1.2, 1.2, 2.2, 1.7, 3.2, 2.2, 4.2,.....?

• there are two series with alternate terms
  (.7,1.2,1.7,2.2, ) and (1.2,2.2,3.2,4.2, )
  both series are AP with cd .5 & 1 respectively
  so next two terms are
  2.2+.5=2.7 & 4.2+1=5.2

• 2.7 alternate increase of 0.5 and 1
• 10 years agoHelpfull: Yes(24) No(2)
• here 2 AP runs alternative..
  one have a difference of .5
  and other have a difference of 1
  
  ans 2.2+.5=2.7
• 10 years agoHelpfull: Yes(11) No(1)
• 2.7... difference between 1st 3rd 5th so on terms is 0.5 and 2nd 4th 6th so on terms is 1.0
• 10 years agoHelpfull: Yes(5) No(0)
• .7+.5=1.2,1.2+.5=1.7,1.7+.5=2.2,2.2+.5=2.7
  answer is = 2.7
• 10 years agoHelpfull: Yes(5) No(1)
• 0.7,1.2,1.2,2.2,1.7,3.2,2.2,4.2,?
  here 0.7,1.2,1.7,2.2 the difference between two adjacent numbers is 0.5 so
  2.2+0.5=?
  so ans: 2.7
  
• 10 years agoHelpfull: Yes(3) No(0)
• 1.2-.7=..5
  2.2-1.2=1.0
  3.2-1.7=1.5
  4.2-2.2=2.0
  moreover
  difference between 2nd and 3rd,4th and 5th ,5th and 6th is 0,0.5,1.0respectively.
  therefore diff. between 6th and 7th will be 1.5
  i.e. 4.2-1.5=2.7

• {.7,1.2,1.2,2.2},{1.7,3.2,2.2,4.2},{2.7,5.2,3.2,6.2} (make 3 groups)
  .7+1=1.7;1.7+1=2.7 (adding 1)
  1.2+2=3.2;3.2+2=4.2 (adding 2)
  1.2+1=2.2;2.2+1=3.2 (adding 1)
  2.2+2=4.2;4.2+2=6.2 (adding 2)
• 10 years agoHelpfull: Yes(1) No(3)
• 2.7
  alternate series of 0.7 increasing with .5
• 10 years agoHelpfull: Yes(1) No(1)
• (0.7,1,2,1.7,2.2) (1.2,2.2,3.2,4.2)
  first set each digit incremented by 0.5
  second set each digit incremented by 1
  so answer is 2.2+0.5=2.7
• 10 years agoHelpfull: Yes(1) No(0)
• .7+.5=1.2
  1.2+.5=1.7
  so answer is 2.7
• 10 years agoHelpfull: Yes(1) No(0)
• if we consider the series in 2 parts,the we get-
  (0.7,1.2,1.7,2.2__) and (1.2,2.2,3.2,4.2,__)
  so for the first one if we add 0.5 to each term,we get the final ans as 2.7 i.e.
  0.7+0.5=1.2
  1.2+0.5=1.7
  1.7+0.5=2.2
  2.2+0.5=2.7
  and the second one will be obtained by adding 1.0 to each term,i.e.----
  1.2+1.0=2.2
  2.2+1.0=3.2
  3.2+1.0=4.2
  4.2+1.0=5.2
  thus the two ans are--2.7 and 5.2

• Ans: 2.7
  this is alternate series.
  .7+.5= 1.2, 1.2+1.0= 2.2, 1.7+1.5= 3.2, 2.2+2.0 = 4.2 ;
  1.2-0= 1.2, 2.2-0.5= 1.7, 3.2-1.0= 2.2, 4.2-1.5= 2.7
  hence ans: 2.7
  
• 10 years agoHelpfull: Yes(0) No(0)
• 2.7 because the series is increasing alternate as 0.5 and 1
  0.7,1.2,1.7,2.2,2.7
  1.2,2.2,3.2,4.2
• 10 years agoHelpfull: Yes(0) No(0)
• difference between them is 0.5,0,1.0,-0.5,1.5,-1.0,2.0....again take difference between differences we get 0.5,1.0,1.5,2.0,2.5,3.0...next difference will be 3.5 so answer is 2.7
• 10 years agoHelpfull: Yes(0) No(0)

• 2.7
  
  the ultimate difference is -1.5
  so, 4.2-1.5=2.7
• 10 years agoHelpfull: Yes(0) No(0)
• Ans: 2.7
  .7+.5=1.2+.5=1.7+.5=2.2+.5=2.7
  1.2+1=2.2+1=3.2+1=4.2
• 10 years agoHelpfull: Yes(0) No(0)
• 2.7.....1st term , 3rd term and so alternate terms increasing by .5.
• 10 years agoHelpfull: Yes(0) No(0)
• from left to right alternately .5 is being added(.7+.5=1.2,1.2+.5=1.7,1.7+.5=2.2,2.2+.5=2.7) so the ans is 2.7.
  
• 10 years agoHelpfull: Yes(0) No(0)
• even digits are with a difference of 1.0
  odd digits are with a difference of .5 hence last digit will be 2.2+.5 = 2.7

  2.7 ans
• 10 years agoHelpfull: Yes(0) No(0)
• two series= .7,1.2,1.7,2.2,next
  & 1.2,2.2,3.2,4.2..........
  next term will be 5th term of 1st series ..the increment of each term of 1st series is .5
  i.e. next term is.....2.2+.5=2.7

• 2.7
  solution---
  0.7+1=1.7
