Question

What is the nth term rule of the linear sequence below?

6, 13, 20, 27, 34, . . .

Answer 1

7n - 1

Explanation:

notice that the difference between adjacent terms is 7.

so nth term is given by:

nth term = first term + (n-1)×difference (n is any number)

= 6 + (n-1)7

= 6+ 7n -7

= 7n - 1

hope this helps :-))
