Arithmetic Sequence

Front

Define arithmetic sequences.

Back

A sequence whose terms change by adding the same number each time.

Front

What is the recursive rule for the arithmetic sequence -10, -3, 4, 11,...?

Back

a_1=-10, a_n=(n-1)+7

Front

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

Back

d = 5

Front

What are the next two terms of the arithmetic sequence 13, 19, 25?

Back

31 and 37

Front

What is a_1 in the sequence -6, -14, -22, -30...?

Back

-6

Front

What is the formula for the nth term of an arithmetic sequence?

Back

a_n = a_1 + (n-1)d, where d is the common difference.

Front

If the first term of an arithmetic sequence is 5 and the common difference is 3, what is the 10th term?

Back

32

Front

How do you find the common difference in an arithmetic sequence?

Back

Subtract the first term from the second term.

Back

d = 3

Front

If the 5th term of an arithmetic sequence is 20 and the common difference is 4, what is the first term?

Back

a_1 = 4.
