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).
