Question

What is the “mean” of this number sequence? 4, 2, 2, 2, 5, 15? A.4 B.5 C.13 D.2

Answer 1

mean = total of number /total number
=4+2+2+2+5+15/6
30/6
=5

hence option b is correct

Answer 2

Number series = 4, 2, 2, 2, 5, 15

Find the sum :

To find the sums, we add up all the numbers

Sum = 4 + 2 + 2 + 2 + 5 + 15 = 30

Find the mean:

Total number of terms is the number of terms we are add

Total number = 5

Mean is the average of the numbers added together

Mean = sum ÷ (total number of terms)

Mean = 30 ÷ 6 = 5

Answer: The mean is (B) 5
