Recursive and Arithmetic Sequences

Front

What does a1 represent?

Back

First term

Front

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

Back

an = -4n + 29

Front

Given the first five terms, write the recursive formula: 15, 12, 9, 6, 3 ....

Back

a1 = 15, an = an-1 - 3

Front

If an+1 represents the third term, which term does an represent?

Back

Second Term

Front

Find the first four terms of the sequence: an = a(n-1) - 18 where a1=10.

Back

10, -8, -26, -44

Front

Define a recursive sequence.

Back

A sequence where each term is defined based on previous terms.

Front

What is an arithmetic sequence?

Back

A sequence in which the difference between consecutive terms is constant.

Front

How do you find the nth term of an arithmetic sequence?

Back

Use the formula an = a1 + (n-1)d, where d is the common difference.

Front

What is the common difference in the sequence: 5, 8, 11, 14...?

Back

3

Front

Write the first three terms of the sequence defined by: a1 = 2, an = an-1 + 5.

Back

2, 7, 12
