Question

Insert 4 arithmetic means between 7 and 22

Answer 1

Answer:

10

13

16

19

Step-by-step explanation:

First of all, arithmetic mean the average of a set of numerical values, as calculated by adding them together and dividing by the number of terms in the set.

Coming to the answer,

Let the 4 arithmetic means be a1 , a2 , a3 , a4. The total number of series is 6

The AP is 7 , a1 , a2 , a3 , a4 , 22

t6 = 22

a + (6-1)d = 22

7+(5)d = 22

5d = 22-7

5d = 15

d = 15/5

d = 3

so , the four arthmetic means are

7+3 = 10

7+6 = 13

7+9=16

7+12 = 19
