Arithmetic Sequence Eoc

What kind of sequence is the pattern 32, 38, 44, 50, 56, ...?

• arithmetic

• geometric

• neither

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

• a_n = 4n + 29

• a_n = -4n + 25

• a_n = -4n + 29

• a_n = 4n + 25

Find the 22nd term of the following sequence:
5, 8, 11, ...

• 14

• 68

• 63

• 71

Find the 25th term of the sequence if a₁ = 5 and d = 0.5

• 18

• 17

• 15

• 14

Find the first term of the given sequence:
a₁₄=68
d=3

• 14

• 20

• 26

• 29

How many coins are in the 30^th stack?

• 92

• 43

• 89

• 60

Given the following sequence, write a formula to determine the nth term.
-16, -11, -6, -1, 4

• f(x) = 5x - 21

• f(x) = -5x - 21

• f(x) = 5x - 16

• f(x) = -5x - 16

What is the recursive formula for a sequence containing the terms:
a₁ = 5 ; a₆ = 20

• a_n = a_{(n - 1)} + 5

• a_n = a_{(n - 1)} ⋅ 3

• a_n = a_{(n - 1)} + 3

• a_n = a_{(n - 1)} - 5

Given the recursive formula, find the first four terms:
a_n = a_n-1 + 5
a₁ = -16

• -16, -21, -26, -31

• 5, -11, -27, -43

• -16, -80, -500, -200

• -16, -11, -6, -1

Which statement best describes an arithmetic sequence?

• Each term can be divided evenly by the previous term.

• Each term after the first is the same multiple of the preceding term.

• Each term after the first is the sum of the two previous terms

• Each term differs for m the preceding term by a constant amount.
