Question

Answer 1

Answer:

37

Step-by-step explanation:

It is the property of arithmetic mean

If we increase variable by same no. that is any constant k then the mean will also be increase by k

For eg.

X x+2

1 3

2 4

3 5

4 6

5 7

15 25

Mean = 15÷5=3

Mean for x+2= 25/5=5

so in this question

Mean =35

Increased no. =2

Then increased mean = 37
