Question

Write the equation that describes the nth term of the following arithmetic sequence: a_n = a_n-1 + 12, a₁ = 20

Then, use the equation to determine the 40th term of the sequence.

Accepted Answer

a_n = 8 + 12n, a₄₀ = 488

Answer

a_n = 20 + 12n, a₄₀ = 500

Answer

a_n = 20 - 12n, a₄₀ = -460

Answer

a_n = 8 - 12n, a₄₀ = -472
