## Number Pyramid 2

Logic puzzles require you to think. You will have to be logical in your reasoning.

 Puzzle ID: #48899 Fun: (2.27) Difficulty: (2.46) Category: Logic Submitted By: westbrook1

This teaser is a mixture of logic and math. In a number pyramid, the numbers 0-9 are each used once and formed into a pyramid, with one digits at the top, and right below it two digits, below those three digits, and below those four, all arranged in pyramid form. I can not show you a pyramid due to formatting issues.

In this puzzle, you will follow the clues given, and using these clues, create a number pyramid. There is only one answer.

Clues:

1. The number at the apex, or top, of the pyramid minus the leftmost number in the fourth row equals 7.

2. The middle, or second, number in the third row minus the rightmost number in the third row equals 4.

3. The four numbers in row 4 sum to 8.

4. In the second row, the rightmost number minus the leftmost number equals 1.

5. The four rightmost numbers in each row sum to 25.

6. The numbers 1 and 2 are not adjacent to each other.

 juggler314 Aug 28, 2011 Very fun! Can't wait for more!! chessgenius Jan 18, 2013 Solved it in 15 min... Thanks for the teaser spikethru4 Jan 20, 2013 Good teaser. Can it be solved logically, without using trial and error? carlm0404 Feb 11, 2016 What do you mean, " trial and error"? You have to list some possible partial cases and eliminate some of them due to noncompliance with clues. carlm0404 Feb 12, 2016 Also, notice the clue that 1 and 2 are not adjacent to each other. I was a little confused by this, although I eventually got the right answer. APPARENTLY this means that, if they are on the SAME ROW, they are not adjacent to each other; the confusion I had was how do you account for "adjacent" w/r to cells in adjacent rows?
