(5,2)=29.
(6,2)=48.
(7,2)=69.
(8,2)=92.
THEN (9,2)=?

• (9,2)=9^2+36=117
  (4,12,20,28..........series is add)

• ans is 125 because......
  (5,20)=10*3-1=29
  i.e 5*2=10 again difference b/w 5and 2= 3 so again 10*3=30.and 30-1=29
  every 1st,3rd,5th odd series works like this
  where as
  (6,2)=6*2=12
  6-2=4
  12*4=48
  so now (9,2) is 5th one it follows 1st series so 9*2=18
  (9-2)=7
  18*7=126
  so ans is 126-1=125

• ans-117..
  as (5,2)=(5^2-2^2) + 8=29
  (6,2)=(6^2-2^2) + 16=48.
  (7,2)=(7^2-2^2) + 24=69.
  (8,2)=(8^2-2^2) + 32=92.
  (9,2)=(9^2-2^2) + 40=117
