Question

Calculate the 10th term of x_n= 2n+1.

Answer 1

Answer:

21

Step-by-step explanation:

Given nth term of an AP, x_n = 2n+1

therefore, 10th term (n=10) = 2x10+1

                                 = 21

Answer 2

Given :-

The 'n'th term of an A.P.(xₙ) = 2n + 1.

To find :-

The 10th term(x₁₀).

Solution :-

xₙ = 2n + 1

Similarly,

x₁₀ = 2(10) + 2

⇒x₁₀ = 20 + 1

⇒x₁₀ = 21
