The expression that represents the nth term of this sequence is 3n - 2

How to determine the nth term of the sequence?

The first five terms of the arithmetic sequence are given as:

1 4 7 10 13

The above sequence has the following properties

  • First term, a = 1
  • Common difference, d = 3

The nth term of the sequence is then calculated using:

an = a + (n -1)d

So, we have:

an = 1 + (n - 1) * 3

This gives

an = 1 + 3n - 3

Evaluate the common terms

an = 3n - 2

Hence, the expression that represents the nth term of this sequence is 3n - 2
