Question

what is the mean of this number sequence 4,2,2,2,5,15

Answer 1

Answer:

Writing the given sequence in ascending order we get,

2, 2, 2, 4, 5, 15

Mean = Sum of all terms / Number of terms

Sum of all terms = 2 + 2 + 2 + 4 + 5 + 15 = 30

Number of terms = 6

Mean = 30 / 6 = 5

Hence the mean of the number sequence is 5.

Answer 2

4+2+2+2+5+15/6

30/6

5

The mean of the numbers 4,2,2,2,5,15 is 5
