8 10 14.5 22.5 35 53?

• 8 + 2 = 10
  10 + (2 + 2.5=4.5) = 14.5
  14.5 + (4.5 + 3.5=8) = 22.5
  22.5 + (8 + 4.5=12.5) = 35
  35 + (12.5 + 5.5=18) = 53
  53 + (18 + 6.5=24.5) = 77.5

• Differences between consecutive terms are 2, 4.5, 8, 12.5, 18
  Again differences between consecutive differential terms are 2.5, 3.5, 54.5, 5.5.
  So, Next one must be 6.5
  Add 6.5 to 18=>24.5
  Add 24.5 to the last term(53) =53+24.5=77.5
