Question

12. Which term of the AP 8, 6, 4, ....... is zero
?​

Answer 1

THE 5th TERM OF THIS AP IS 0

mark my answer as the brainiest if you find it helpful

Answer 2

Solution :

• First term (a) = 8
• Common difference (d) = 6 - 8 = -2

Now,

Which term of AP is 0 :-

0 = a + (n - 1)d

0 = 8 + (n - 1) ×(-2)

- 8 = (n - 1) × (-2)

- 8/-2 = n - 1

4 = n - 1

n = 5

Hence

• 5th term of AP is 0
