Question

find the value of middle term of the following ap, - 6,-2,2.......,58​

Answer 1

Answer:

26

Step-by-step explanation:

-6, -2, 2,........58.

a = -6. d = 4 last term = 58

an = a + (n-1)d

58 = -6 + (n-1)(4)

58 + 6 = (n-1)(4)

64 = (n-1)(4)

n - 1 = 64/4

n - 1 = 16

n = 16 + 1

n = 17

the middle term (n+1) /2. = (17+1)/2 = 9

the 9th term of the AP = a9 = a + 8d

= -6 + 8(4)

= - 6 + 32

= 26

the middle term = 26
