Check the pattern:
121 = 11 x 11
144 = 12 x 12
169 = 13 x 13
196 = 14 x 14
So each number is a square of consecutive numbers: 11, 12, 13, 14
Next number will be square of 15
15 x 15 = 225

To find the average, we need to first convert each fraction to a decimal:
5/6 = 0.83
4/3 = 1.33
3/4 = 0.75
Then, add the decimals and divide by the number of values:
0.83 + 1.33 + 0.75 = 2.91
2.91 ÷ 3 = 0.97
Now, convert the average back to a fraction:
0.97 ≈ 35/36

The average of the first n natural numbers is given by (n + 1) / 2.
For n = 97:
Average = (97 + 1) / 2
= 98 / 2
= 49

The sum of all interior angles in any triangle is always 180 degrees.
A fundamental rule in Euclidean geometry, regardless of the triangle's shape (e.g., right, equilateral, scalene).
This property is known as the Angle Sum Property.
