Mathematicians are not the people who find Maths easy; they are the people who enjoy how mystifying, puzzling and hard it is. Are you a mathematician? Comment recorded on the 19 October 'Starter of the Day' page by E Pollard, Huddersfield: "I used this with my bottom set in year 9. To engage them I used their name and favorite football team (or pop group) instead of the school name. For homework, I asked each student to find a definition for the key words they had been given (once they had fun trying to guess the answer) and they presented their findings to the rest of the class the following day. They felt really special because the key words came from their own personal information." Comment recorded on the 28 May 'Starter of the Day' page by L Smith, Colwyn Bay: "An absolutely brilliant resource. Only recently been discovered but is used daily with all my classes. It is particularly useful when things can be saved for further use. Thank you!" |

Go MathsLearning and understanding Mathematics, at every level, requires learner engagement. Mathematics is not a spectator sport. Sometimes traditional teaching fails to actively involve students. One way to address the problem is through the use of interactive activities and this web site provides many of those.

Here is a reminder of some facts that may help you answering the questions in this exercise.
An arithmetic sequence, sometimes called an arithmetic progression, is a sequence of numbers such that the difference between the consecutive terms is constant. For instance, the sequence 8, 11, 14, 17, 20, 23, . . . is an arithmetic sequence with common difference of 3.
The first term of the sequence can be written as u1
The nth term of the sequence can be written as un
The common difference is usually written as d
The formula for finding the nth term is un=u1+(n-1)d
The formula for finding the sum of n terms is Sn=½n(2u1+(n-1)d)

"For level 2 of this activity, it's not clear how the answer needs to be entered. In the help notes they make reference of things with subscripts. Guidance of the format to enter for the answer is needed.
[Transum: Thanks for your feedback Sarah. For level 2 the answer should be typed in as an expression (no equals sign) in its simplest form. For example, an answer might be '7n' or '5n-2'. No subscripts are required.]"
