Question

In the following A.p find the missing term in the 5 , _ , _ , 9 1 /2​

Answer 1

Answer:

It is... 5 , 13\2 , 8, 9 1\2

Step-by-step explanation:

As the given terms are in AP,

  it will be in form of,

             a , a+d , a+2d , a+3d ,...so on

  By this, we can say

                        a = 5

and given that 4th term is 9 1\2 = 19\2

                   4th term = a+3d = 19\2

                                      5+3d = 19\2

                                         3d = 19\2 - 5

                                         3d = 9\2

                                           d = 3\2

 As we have 'a' and 'd' values we can get 2nd and 3rd term,

           2nd term = a+d = 5+ 3\2 = 13\2

            3rd term = a+2d =5 + 2x3\2 = 8
