Question

Write a recursive rule and a explicit rule for the sequence I really need help

Answer 1

Answer

y = 6x

Explanation

To write a recursive or explict rue for this sequence, we need to firstly examine the given sequence.

If we let money spent = y and number of weeks = x

when x = 1, y = 6

when x = 2, y = 12

when x = 3, y = 18

when x = 4, y = 24

We can easily see that as x increases by units of 1, the y increases by corresponding units of 6.

A rule that will work for this is that

y = 6x

so that, when x = 1, y = 6(1) = 6 (as it is on that graph)

when x = 2, y = 6(2) = 12 (as it is on that graph again)

And so on.

Hope this Helps!!!
