Exam Style Question on Sequences
A mathematics exam-style question with a worked solution that can be revealed gradually
Question id: 2. This question is similar to one that appeared in an IB Standard paper in 2010. The use of a calculator is allowed.
The first three and last terms of an arithmetic sequence are \(7,13,19,...,1357\)
(a) Find the common difference.
(b) Find the number of terms in the sequence.
(c) What is the sum of the sequence.
The worked solutions to these exam-style questions are only available to those who have a Transum Subscription.
Subscribers can drag down the panel to reveal the solution line by line. This is a very helpful strategy for the student who does not know how to do the question but given a clue, a peep at the beginnings of a method, they may be able to make progress themselves.
This could be a great resource for a teacher using a projector or for a parent helping their child work through the solution to this question. The worked solutions also contain screen shots (where needed) of the step by step calculator procedures.
A subscription also opens up the answers to all of the other online exercises, puzzles and lesson starters on Transum Mathematics and provides an ad-free browsing experience.
