Arithmetic Sequences Practice

Find the common difference of the arithmetic sequence 14, 20, 26, ...

Is the sequence 3, 5, 7, ... an arithmetic sequence?

Is 3, 15, 75, ... an arithmetic sequence?

Formula for the nth term in the sequence 12, 20, 28, ...?

Formula for the nth term in the sequence -4, -9, -14, ...?

Find the common difference: -34, -29, -24, -19, ...

Given the sequence:
 25, 21, 17, 13,...
Write the explicit equation that models the sequence.

Find a₂₀ in the arithmetic sequence: 5, 12, 19, 26...

Sequence: 2, 5, 8, 11, ... Which explicit formula models the sequence? Options: aₙ = 3 - 11(n - 1), aₙ = 2 + 3(n - 1), aₙ = 11 - 3(n - 1), aₙ = 3 + 2(n - 1)

Select the explicit rule that represents the sequence:

a_n = 6 + 5(n - 1)

a_n = 4 + 6(n - 1)

a_n = 6 - 4(n - 1)
