7/2 - 5/2 = 2/2 = 1

9/2 - 7/2 = 2/2 = 1

Answer 2

Answer:

The sequence is an A.P.

Step-by-step explanation:

If,

  $\frac{5}{2} - \frac{3}{2} = \frac{7}{2} - \frac{5}{2} = \frac{9}{2} - \frac{7}{2}$

then the sequence is an A.P.

As ,

       $\frac{5}{2} - \frac{3}{2} = \frac{7}{2} - \frac{5}{2} = \frac{9}{2} - \frac{7}{2}$ = 1

 So, The sequence is an A.P.
