Answer 2

Answer:

• 30th term of A.P. is -77.

Step-by-step explanation:

Given:

• a₁ = 10
• a₂ = 7
• d = a₂ - a₁ = 7 - 10 = -3

To Find:

• 30th term of A.P.

Now, we know that,

⇒ aₙ = a + (n - 1)d

⇒ a₃₀ = 10 + (30 - 1)-3

⇒ a₃₀ = 10 + (29)-3

⇒ a₃₀ = 10 - 87

⇒ a₃₀ = -77

Hence, 30th term of A.P. is -77.
