5,6,6.5,6.5,8,7,9.5,?

• In above series, there are 2 alternate series.
  1st series is : 5,6.5,8,9.5 , if you observe it carefully you will find that next digit is increased by 1.5 eg.5,6.5(5+1.5),8(6.5+1.5),9.5(8+1.5)
  2nd series is : 6,6.5,7,? here next digit is previous digit +0.5
  e.g 6, 6.5(6+0.5), 7(6.5+0.5), 7.5 (7+0.5)
  Hence ans is "7.5".

• Two different AP Series say A(n) and B(n)
  So above sequence is as A(n),B(n),A(n),B(n),A(n),B(n),A(n),B(n)
  
  So,
  
  A(n)-> 5, 6.5, 8, 9.5 (difference = 1.5)
  B(n)-> 6, 6.5, 7, ? (difference = 0.5)
  
  So ultimately next number will be from series B(n) and will be 7.5 (7+0.5)

• 7.5
  it consist two series
  first is
  5,6.5,8...difference of 1.5
  and second is
  6,6.5,7...difference of .5
