This is a mathematical challenge, and it's been said that:
* If you're an engineer, you should be able to solve it in (under) three minutes, * if you're an architect, in three hours; * if you're a doctor, in six hours; * if you're an accountant, in three months and * If you're a lawyer, probably never. What is the missing number in this logical series? 1, 2, 6, 42, 1806, ____??? |

Got it within 10 mins.
The sequence starts with 1 then...... (1*1) + 1 = 2 (2*2) + 2 = 6 (6*6) + 6 = 42 (42*42) + 42 = 1806 (1806*1806) + 1806 = 3263442 Hence, answer is 3263442. I'm not an engineer, or an architect, or a doctor, or an accountant, or even a lawyer. I'm just a business student.

But I solve it differntly and within 3-5 minutes.
The sequence starts with 1 then...... (After 1 comes 2) 2 * 1 = 2 (After 2 comes 3) 2 * 3 = 6 (After 6 comes 7) 6 * 7 = 42 (After 42 comes 43) 42 * 43 = 1806 (After 1806 comes 1807) 1806 * 1807 = 3263442 Hence, answer is 3263442. But your sequence is more appropriate. Well done |

What was your pattern to solve it ?
One more and let me see who solve it first. IF 7 + 6 = 113 9 + 1 = 810 5 + 3 = 2 8 9 + 6 = 315 Then, 7 + 2 =? Last edited by Princess Royal; Friday, March 05, 2010 at 08:44 PM. |

7 + 6 = 113
9 + 1 = 810 5 + 3 = 2 8 9 + 6 = 315 7 + 2 = 59 Add the two no. and place the sum at the last, the first no. is the difference between the two. Time: 22 seconds I had stop watch with me this time hehehe
