Answer:

subtract 6

Explanation:

note there is a common difference between consecutive terms, that is

45 - 51 = - 6

39 - 45 = - 6

33 - 39 = - 6

27 - 33 = - 6

21 - 27 = - 6

the rule being used to make the pattern is subtract 6

this is an arithmetic sequence for which an nth term rule can be found
