Answer:

(a) 2

(a) 2(b) 4

(a) 2(b) 4(c) 5

(a) 2(b) 4(c) 5(d) 7

(a) 2(b) 4(c) 5(d) 7(e) 4.25

Step-by-step explanation:

(a)The first three counting numbers are 1, 2 and 3

So, average =

 \frac{1 + 2 + 3}{3}  =  \frac{6}{3}  = 2

(b)The first four odd numbers are 1, 3, 5 and 7

So, average =

 \frac{1 + 3 + 5 + 7}{4}  =  \frac{16}{4}  = 4

(c)The first five odd numbers are 1, 3, 5, 7 and 9

So, average =

 \frac{1 + 3 + 5 + 7 + 9}{5}  =  \frac{25}{5}  = 5

(d)The first six even numbers are 2, 4, 6, 8, 10 and 12

So, average =

 \frac{2 + 4 + 6 + 8 + 10 + 12}{6} =  \frac{42}{6} = 7

(e)The first four prime numbers are 2, 3, 5 and 7

So, average =

 \frac{2 + 3 + 5 + 7}{4}  =  \frac{17}{4}  = 4.25
