Question

11th term of the ap :-3,1/2,2is

Answer 1

First we need to check if the given sequence is AP or not.

so we find difference between consecutive terms.

(1/2)-(-3)=0.5+3=3.5

(2)-(1/2)=2-0.5=1.5

As you can see that common difference is not equal in both cases so given sequence is not an AP. Hence we won't be able to find the 11th term.

Answer 2

Answer:

• 11th term of given AP is -22.

Step-by-step explanation:

Given:

• AP = 3, 1/2, 2
• a = 3
• a₂ = 1/2

To Find:

• 11th term of AP

Now, we know that

⇒ d = a₂ - a₁

⇒ d = 1/2 - 3

⇒ d = -5/2

Now, we will find 11th term of AP,

⇒ aₙ = a + (n - 1)d

⇒ a₁₁ = 3 + (11 - 1)-5/2

⇒ a₁₁ = 3 + (10)-5/2

⇒ a₁₁ = 3 - 25

⇒ a₁₁ = -22

Hence, 11th term of given AP is -22.
