• 7^2=49 6
  5^2=25 6-2=4
  6^6=36 4+1=5(diff -2+3=1)
  9^2=81 5-0=5
  diff(5+3)
  8^2=64

• 7^2=49, 7-1=6, 6*2^2=24+1=25
  5^2=25, 5-1=4, 4*3^2=36
  6^2=36, 6-1=5, 5*4^2=80+1=81
  9^2=81, 9-1=8, 8*5^2=200
  might be the answer

• make pairs
  in first pair 7^2=49, 7-1=6
  similarly in next pairs
  5^2=25, 5-1=4
  6^2=36, 6-1=5
  9^2=81, 9-4=5
  as there is difference between 9 and 6 is 3 so we calculate for 12
  so next calculation is
  12^2=144,
