The pattern here followed is :

6 $$\times 2 + 2^2$$ = 16

16 $$\times 3 + 3^2$$ = 57

57 $$\times 4 + 4^2$$ = 244

244 $$\times 5 + 5^2$$ = 1245

1245 $$\times 6 + 6^2$$ = 7506

Similarly,

4 $$\times 2 + 2^2$$ = 12

12 $$\times 3 + 3^2$$ = 45

45 $$\times 4 + 4^2$$ = 196

196 $$\times 5 + 5^2$$ = 1005
