What is the next number of the following sequence
22, 19.5, 21.45, 33, 30.5, 33.55, 44, 41.5,......?

• 22-2.5=19.5
  22-0.55=21.45
  and
  33-2.5=30.5
  33+0.55=33.55
  Similarly,
  44-2.5=41.5
  44-0.55=43.45
  The missing term is 43.45

• 1st - 4th = -11
  4th - 7th = -11
  2nd - 5th = -11
  5th - 8th = -11
  3rd - 6th = -12.10
  6th - 9th = -12.10
  so 9th term should be 45.65

• here it is adding or subtracting some values
  
  22-2.5=19.5
  22-0.55=21.45
  and
  33-2.5=30.5
  33+0.55=33.55
  so,
  44-2.5=41.5
  44-0.55=43.45
  The missing term is 43.45

• there are 3 series... 22,33,44--- cd= 11
  19.5,30.5,41.5--- cd=11
  and--- 21.45,33.55----- cd=12.1.. so last is== 33.55+12.1=45.65

• 22-19.5=2.5
  21.45-19.5=1.95
  33-21.45=11.5
  33-30.5=2.5
  33.55-30.5=3.05
  44-33.55=10.45
  44-41.5=2.5
  now diff of 3.05 & 1.95 is 1.1 add 3.05 with 1.1 result is 4.15 then add 4.15 with the last number in the given sequence i.e 41.5+4.15=45.65
  The answer is 45.65

• 22-2.5=19.5
  22-0.55=21.45
  and
  33-2.5=30.5
  33+0.55=33.55
  Similarly,
  44-2.5=41.5
  44-0.55=43.45
  The answer 43.45

• 45.65..
  21.45-19.5=1.95
  33.55-30.5=3.05
  3.05-1.95=1.1
  3.05+1.1=4.15
  41.5+4.15=45.65

• 19.5+2.5=22
  21.45+0.55=22
  &
  30.5+2.5=33
  33.55-0.55=33
  so
  41.5+2.5=44
  44-0.55=43.45

• 22-33-44 : diff of 11
  19.5- 30.5 - 41.5 : diff of 11
  21.45 - 33.55 - ? : diff of 12.10..
  so answer is : 45.65

• 45.45
  22+11=33, 33+11=44
  19.5+11=30.5, 30.5+11=41.5
  21.45+12=33.45, 33.45+12=45.45
