Question

find the value of the middle term of the AP:3,8,13,......,153.​

Answer 1

Answer:

middle term  = 73

Step-by-step explanation:

a =3 ,  d = 8 -3       l = 153

              = 5

 n  = ( l -a )  /d      + 1

     =  (153 - 3) / 5    +1

     = 30 + 1

     = 31

∴ the middle term  =  15

15th term  = a + 14d

                 = 3 + 14 (5)

                = 3 + 70

               = 73
