Back

74, 73

Front

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

Back

The nth term can be found using the formula: a_n = a_1 + (n-1)d, where a_1 is the first term and d is the common difference.

What is the first term in the sequence: 39, 32, 25, 18?

Back

The first term is 39.

Back

False. Each figure has 7 fewer squares than the one before it.

Front

If the first term of an arithmetic sequence is 5 and the common difference is 3, what is the 4th term?

Back

The 4th term is 14.

Front

What is the rule for the sequence: 10, 15, 20, 25?

Back

The rule is to add 5 to the previous term.
