Find the value of the middle term of the following AP: -6 , -2 ,2 ,.....,58.

Answer»

Answer:

26

Step-by-step EXPLANATION:

a= -6

d = a2-a1 = -2+6 = 4

an (L) = 58

an = a+(n-1)d

58= -6+(n-1)4

n= 17

middle TERM = n+1/2

= 17+1/2 = 9

so ' a+8d = 6+8(4)=26.

therefore the middle term of the AP is 26.
