A user asks a language model to calculate the mean square of the numbers 2, 4, and 6. The model provides the following step-by-step response:

Step 1: Square each number: 2²=4, 4²=16, 6²=36. Step 2: Sum the squares: 4 + 16 + 36 = 56. Step 3: Sum the original numbers: 2 + 4 + 6 = 12. Step 4: Divide the sum of the squares by the sum of the original numbers: 56 / 12 ≈ 4.67.

Which step introduces the fundamental error in the procedure for calculating the mean square?

A user asks a language model to calculate the mean square of the numbers 2, 4, and 6. Arrange the following computational steps into the correct logical sequence that the model should follow to arrive at the correct answer.
