The first term of a sequence is 13

the term-to-term rule is 'takeaway 5'

work out the 4th term

- 2

Step-by-step explanation:

Using the term - to - term rule of subtract 5

This means to find a term in the sequence, subtract 5 from the previous term.

Given a (1) = 13, then

a (2) = a (1) - 5 = 13 - 5 = 8

a (3) = a (2) - 5 = 8 - 5 = 3

a (4) = a (3) - 5 = 3 - 5 = - 2

The fourth term is - 2
