Answer 1

Answer: IT IS NOT AN AP

Step-by-step explanation:

2, 5/2,3,7/3

GIVEN: a=2 , a2= 5/2 , a3= 3, a4=7/3

SOLUTION : a2 - a = 5/2 - 2

                                =5-4/2        (cross multiplication)

                                = 1/2  

                   a3-a2 = 3-5/2

                              = 6-5/2

                              = 1/2

                   a4-a3 = 7/3 - 3

                              = 7-9/3

                              = 2/3

                      ∴ It is not an AP
