| 3+12 = 15+12 = 27 -- -3,15,27. 6+25 =31+25 = 56 --- 6,31,56. 9+36 = 45+36 = 81 --- 9,45,81. |

| Logic is mid = (up+end)/2. (3+27)/2 = 15. (6+56)/2 = 31. So (9+81)/2 = 45. |

| (27+3) = 15. (6+56) = 31. Then (81+9) = ? |

| (15*2) -3=27. (31*2) -6=56 //gap between these numbers (15 to 31) is 16. (45*2) -9=81 //gap between these numbers (31 to 14) is 14. |
