Arithmetic Sequences Explicit Rule

Select the explicit rule that represents the sequence.

• 11 - 68(n - 1)

• 68 - 9(n - 1)

• 68 - 11(n - 1)

• 9 + 68(n - 1)

Select the explicit rule that represents the sequence.

• 56.2 + 5.1(n + 1)

• 5.1 + 5.1(n - 1)

• 56.2 + 5.1(n - 1)

• 56.2 + 4.1(n - 1)

Given the sequence:
 25, 21, 17, 13,...
Write the explicit equation that models the sequence.  (Hint:  Simplify your equation.)

• a_n = 4n + 29

• a_n = -4(n-1) + 25

• a_n = -4n + 29

• a_n = 4n + 25

What is the rule (explicit equation) for the n^th term given 
60, 55, 50, 45, ...

• a_n= -5+60n

• a_n= -5(n-1)+60

• a_n= -5n+65

• a_n= 5n+55

Find the explicit rule for an arithmetic sequence if the 6th term is -38 and the 14th term is -110

• a_n=7-9(n-1)

• a_n=-9+7(n-1)

• a_n=-83+9(n-1)

• a_n=9-83(n-1)

Write the explicit rule for this situation in simplified form.

• f(n) = −8n + 60

• f(n) = 8n + 44

• f(n) = −8n + 52

• f(n) = f(n − 1) − 8

Select the explicit rule that represents the sequence.

• 6 + 5(n - 1)

• 4 + 6(n - 1)

• 6 - 4(n - 1)

Select the explicit rule that represents the sequence.

• 14(-3)(n - 1)

• 3 - 14(n - 1)

• 14 - 3(n - 1)

The next two terms of the sequence 12,17,22,27 are

• 28 and 33

• 29 and 34

• 32 and 37

• 30 and 35

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
