Answer 2

Answer:

A.P=5,7,9,11,13 ...................

Step-by-step explanation:

a5=13

a9=21

a9=a+8d =>equation 1

a5=a+4d =>equation 2

(1-2)

21=a+8d                                                            a9=21

13=a+4d                                                            a5=13

8=4d                                                                 a cancels  

d=2

Substituting d=2 in equation 2

13=a+(4*2)

=13=a+8

a=5
