Answer:

Hey,friend thanks for asking this question.Your answer is below.

Step-by-step explanation:

As we know, every odd number has a difference of 2.

Let the first number A= a

then 2nd number B= a+2

3rd number C =a+4

4th number D= a+6

5th number E= a+8

or, (a+a+2+a+4+a+6+a+8)÷5 =21

or,(5a+20)÷5 =21

or,(5a+20) = 21×5

or,(5a+20) = 105

or, 5a= 105-20

or, 5a= 85

therefore, a= 85÷5 = 17

a= 17

b=19

c=21

d=23

e= 25.

product of A and E= 17×25

=425(answer).
