WebSequences: nth term Videos 288, 289 on www.corbettmaths.com Question 4: Here are the nth terms of 4 sequences. Sequence 1 nth term 4n + 3 Sequence 2 nth term 7n + 1 Sequence 3 nth term 14n Sequence 4 nth term 8n - 1 For each sequence state whether the numbers in the sequence are A Always multiples of 7 S Sometimes multiples of 7 WebTo find the nth term, first calculate the common difference, d. Next multiply each term number of the sequence (n = 1, 2, 3, …) by the common difference. Then add or subtract a number from the new sequence to achieve a copy of the sequence given in the question.

First of all, write your position numbers (1 to 5) above the sequence (leave a gap between the two rows) Notice that the sequence is going down by 2 each time, so times your position numbers by -2. Put these into the 2nd row.
