| I didn't get how the answer is 228. Can you please explain ? | |

| Initial value = 7 7 x 1 + 1 = 8 8 x 2 + 2 = 18 18 x 3 + 3 = 57 57 x 4 + 4 = 232 (But given number 228 is out of pattern) 232 x 5 + 5 = 1165 1165 x 6 + 6 = 6996 ... and so on. Hope you understand the logic behind this problem. Have a nice day? |

| The given series 7, 8, 18, 57, 228, 1165, 6996 And the given series in the format of A, AX1+1, BX2+2, CX3+3, DX4+4, EX5+5, FX6+6, GX7+7 BECAUSE CHECK THE SERIES A=7 AX1+1=7X1+1=8 BX2+2=8X2+2=18 CX3+3=18x3+3=57 Dx4+4=57x4+4=232 < Here is the wrong> Ex5+5=232x5+5=1165 This is the process. |

| It can also be done as: A, (A+1)X1, (B+1)X2, (C+1)X3, (D+1)X4, (E+1)X5, (F+1)X6. i.e., A = 7. B = (7+1)X1 = 8. C = (8+1)X2 = 18. D = (18+1)X3 = 57. E = (57+1)X4 = 232. F = (232+1)X5 = 1165. |

| Can any one solve this for me? 96, 169, 144, 121, 101 find the wrong number. |
|
| Girish said: (Jan 4, 2018) | |
| @Suvra Saurav I think may be 96 is 196. Because 196- 14^2. 169- 13^2 144- 12^2 121- 11^2 And there is "101" wrong number. |
|
| Geetika Rana said: (Apr 13, 2018) | |
| I agree @Girish. I also have the same value 196. |
