Number Pyramid To solve this puzzle, each number must be equal to the sum of the two numbers below. 10.7 5.4 5.3 2.8 -2.6 2.7 1.9 0.9 1.7 1.0

To solve this number pyramid puzzle, we'll fill in each level of the pyramid such that each number is the sum of the two numbers directly below it. We'll work from the bottom up.
Here's the structure of the given number pyramid puzzle:

Bottom Row (Given):

− 2.6 , 2.7 , 1.9 , 0.9 , 1.7 , 1.0


Second Row from the Bottom:

First pair: − 2.6 + 2.7 = 0.1
Second pair: 2.7 + 1.9 = 4.6
Third pair: 1.9 + 0.9 = 2.8
Fourth pair: 0.9 + 1.7 = 2.6
Fifth pair: 1.7 + 1.0 = 2.7


Third Row from the Bottom:

First pair: 0.1 + 4.6 = 4.7
Second pair: 4.6 + 2.8 = 7.4
Third pair: 2.8 + 2.6 = 5.4
Fourth pair: 2.6 + 2.7 = 5.3


Fourth Row from the Bottom:

First pair: 4.7 + 7.4 = 12.1
Second pair: 7.4 + 5.4 = 12.8
Third pair: 5.4 + 5.3 = 10.7


Top of the Pyramid:

First pair: 12.1 + 12.8 = 24.9
Second pair: 12.8 + 10.7 = 23.5



This method of constructing the pyramid ensures that each number on top is the sum of the two numbers directly beneath it, aligning with the rules provided in the question. If you follow along and substitute the numbers carefully, you will reconstruct a correct number pyramid.
