One of my last Algebra 2 units before state testing was arithmetic and geometric sequences and series. Our students are given the formulas for the nth term and the sum of the first n terms, but they are given no explanation for what each variable represents. So, I like to spend an entire class period discussing what each variable represents. Then, we look at word problems and label all of the information with the correct variable. The kids hate it, but it really helps them in the long run…

Sequence and series formulas are related to different types of sequences and series in math. A sequence is the set of ordered elements that follow [...]

Learn the general form of the arithmetic series formula and the difference between an arithmetic sequence and an arithmetic series. Discover the partial sum notation and how to use it to calculate the sum of n terms.

This is a full guide to finding the general term of sequences. There are examples provided to show you the step-by-step procedure for finding the general term of a sequence.

A KS3-4 worksheet with questions on linear sequences, including generating a sequence, finding the nth term and deciding if a number is in a sequence.

One of my goals as a math teacher is to present real-life math every chance I get. It is not always easy, I have to admit. When I was in college and the earlier part of my teaching career, I was al…

How to find nth term of increasing Linear (Arithmetic) Sequence QUESTION: a) Write first four terms of a sequence with first term 1 and Term-to-Term rule ‘add 11’. b) Find the 15th term. SOLUTION: a) First term = 1 (given) As Term-to-Term Rule is ‘add 11’, so Second term = First term + 11 ⇒ 1 + 11… Read More »How to find nth term of increasing Linear(Arithmetic) Sequence
