Finding the nth term

Sometimes, rather than finding the next number in a linear sequence, you want to find the 41^st number, or 110^th number, say.

Writing out 41 or 110 numbers takes a long time, so you can use a general rule.

To find the value of any term in a sequence, use the n^th term rule.

Question

What is the n^th term of this sequence?

Reveal

For example, to find the 10^th term, work out 5 × 10 = 50. To find the 7^th term, work out 5 × 7 = 35

So the 41^st term is 5 × 41 = 205 and the 110^th term is 5 × 110 = 550
