Answer:

The value of p is -4

Step-by-step explanation:

TO FIND :  The value of p

GIVEN: 3p+7, 2p+5, and 2p+7

Arthametic mean: The a,b,c are in A.P ,when b-a=c-b

                                                                           2b=a+c

         The given values are 3p+7,2p+5 and 2p+7

                                              2b=a+c    

                                             2(2p+5)=3p+7+2p+7

                                             4p+10=5p+14\\4p-5p=14-10\\-p=4\\p=-4

                 a=3p+7                                             a=3(-4)+7\\a=-12+7\\a=-5

                b=2p+5\\b=2(-4)+5\\b=-8+5\\b=-3

                c=2p+7\\c=2(-4)+7\\c=-8+7\\c=-1

The values of a, b, c are -5,-3,-1

The value of p is -4
