What is the arithmetic mean of 18, 12, 14, 26, 5?

Question

Please help me to find the geometric and arithmetic mean of 18, 12, 14, 26, 5.

Answer 1

Arithemetic mean of list of elements is sum of elements/ number of elements.

Arithemetic mean = (18+12+14+26+5)/5

= 75/5

= 15

Arithemetic mean of 18, 12, 14, 26, 5 is 15.

Geometric mean of a list of numbers is (product of elements)^{1/(numbers of elements)}

Geometric mean of five numbers is fifth root of their product.

Given numbers are 18, 12, 14, 26, 5.

Geometric mean = fifth root(18 * 12 * 14 * 26 * 5)

= (393120)^1/5

=13.1493.

Geometric mean of 18, 12, 14, 26, 5 is 13.1493.
