How do you find the mean of the number sequence 4, 2, 2, 2, 5, 15?

by

To calculate the mean of a number sequence, you follow a straightforward process:

  1. Add all the numbers together: In this case, the sequence is 4, 2, 2, 2, 5, 15. So, you sum them up:
    • 4 + 2 + 2 + 2 + 5 + 15 = 30
  2. Count how many numbers are in the sequence: As we can see, there are 6 numbers:
    • 4, 2, 2, 2, 5, 15 → Total = 6
  3. Divide the total by the number of values: Now that we have the sum (30) and the count of numbers (6), we can find the mean:
    • Mean = Total Sum / Count = 30 / 6 = 5

So, the mean of the number sequence 4, 2, 2, 2, 5, and 15 is 5.

This mean value gives you a sense of the average of the numbers in this sequence, providing a quick insight into the overall trend of the numbers involved.
