  7.2,2.2,3.2,16,11,12,60,55,56,....
  take 3 at a time...
  I.e.
  7.2,2.2,3.2 :
  (7.2-2.2)=5,(2.2+1=3.2),3.2*5=16...
  now , next 3..proceed in same ..16-5=11+1=12*5=60

• 7.2 ,2.2 ,3.2 => (5+2.2, 2.2, 2.2+1)
  16, 11, 12, => (5+11, 11, 11+1) => here, 11= 2.2*5
  60 ,55 ,56 => (5+55, 55, 55+1) => here, 55=11*5
  280, 275,276 => (5+275, 275,275+1) => here 275=55*5
  so ans is 280
