the answer would be 3.......

Answer 2

Answer:

Step-by-step explanation:

a = 2p+1

a2 = 13       d = 13-2p-1 = 12-2p

a3 = 5p-3

So,

        a3 =  a+(n-1)d

         5p-3 = 2p+1+(3-1)(12-2p)

         5p-3 = 2p+1+2(12-2p)

         5p-3 = 2p+1+24-4p

         5p-3 = - 2p+25

        5p+2p = 28

       7p = 28

      p = 28/7 = 4

Hence, option (a) is the correct answer.
