a top row of 1 number resting on a second row of 2 sitting on a third row
of 3 supported by a bottom row of 4. For example, a Number Pyramid

Given the clues below, can you determine the composition of Number
Pyramid 10?
 The three numbers in the top two rows of the pyramid sum to 15.
 Neither 7 nor 9 is the number second from the left in the bottom row.
 The rightmost number in row 2 minus the leftmost number in row 4
equals 3.
 The four numbers in row 4 sum to 26.
 The rightmost number in row 4 of Number Pyramid 10 minus the
leftmost number in row 3 equals 5.
 The number at the apex of the pyramid minus the middle number in row 3
equals 4.
