A set S = {2, 5, 7, 15, 21, 23, 32}. Find arithmetic mean of S.1. 102. 153. 214. 23

Answer» Correct Answer - Option 2 : 15

Given:

S = {2, 5, 7, 15, 21, 23, 32}

Formula Used:

Arithmetic mean = (Sum of terms)/(Number of terms)

Calculations:

S = {2, 5, 7, 15, 21, 23, 32}

Number of terms = 7

Arithmetic mean = (Sum of terms)/(Number of terms)

Sum of terms = {2 + 5 + 7 + 15 + 21 + 23 + 32} = 105

⇒ Arithmetic mean of S = 105/7 = 15

∴ The arithmetic mean of S is 15.
