## Arithmetic Mean - Basic

In mathematics and statistics, the arithmetic mean, or simply the mean or the average, is the sum of a collection of numbers divided by the count of numbers in the collection. The collection is often a set of results of an experiment or an observational study, or frequently a set of results from a survey.

Q1.  A number is the reciprocal of the other. If the arithmetic mean of the two numbers be 13/12 , then the numbers are

•   1/4 , 4/1
•  3/4 , 4/3
•  2/5 , 5/2
•   3/2 , 2/3

3/2 , 2/3

Q2.  The arithmetic mean of first n natural number

•  (n - 1)/2
•  (n + 1)/2
•  n/2
•  n

(n + 1)/2

Q3. The four arithmetic means between 3 and 23 are

•   5, 9, 11, 13
•  7, 11, 15, 19
•  5, 11, 15, 22
•  7, 15, 19, 21

7, 11, 15, 19

Q4.  The mean of the series a, a + nd, a + 2nd is

•   a + (n-1)D
•   a+nd
•  a+(n+1)d
•  None of these

a+nd

Q5.  If n A.M. s are introduced between 3 and 17 such that the ratio of the last mean to the first mean is 3 : 1, then the value of n is

•  6
•  8
•  4
•  None of these

8
