Sequences Algebra

Write the EXPLICIT rule for the arithmetic sequence

-10, -3, 4, 11,...

• a_n = 10n + 17

• a_n = 7n - 17

• a_n = -7n + 17

• a_n = 7n + 3

Identify a₁ and d for the sequence
-5, -2, 1, 4, ...

• a₁ = 3 and d = -5

• a₁ = -8 and d = 3

• a₁ = -5 and d = 3

• a₁ = -5 and d = -3

Find the 25th term of the Arithmetic Sequence 2, 6, 10, 14, ...

Find the 20th term of the Arithmetic Sequence 8, 5, 2, -1, ...

Is the sequence arithmetic: -3, 3, -3, 3, ...

• Yes

• No

Select the explicit rule that represents the sequence.

• 6 + 5(n - 1)

• 4 + 6(n - 1)

• 6 - 4(n - 1)
