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 24 May 'Starter of the Day' page by Ruth Seward, Hagley Park Sports College: "Find the starters wonderful; students enjoy them and often want to use the idea generated by the starter in other parts of the lesson. Keep up the good work" Comment recorded on the 2 May 'Starter of the Day' page by Angela Lowry, : "I think these are great! So useful and handy, the children love them.

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 u_{1}
The n^{th} term of the sequence can be written as u_{n}
The common difference is usually written as d
The formula for finding the n^{th} term is u_{n}=u_{1}+(n1)d
The formula for finding the sum of n terms is S_{n}=½n(2u_{1}+(n1)d)
