Question

The first five terms of an arithmetic sequence are 5, 11, 17, 23, 29. What is the rule for the nth term of this sequence?

Answer 1

Answer:

53

Step-by-step explanation:

Since each number is getting 6 added to it, you need to multiply the increment times how many more numbers there are. So for this, you need to multiply 6 x 4 to get 24. You now add 24 to 29 to get 53.

Answer 2

Answer:

a'n=6n-1

Step-by-step explanation:

If you plug in each value like value two for example it will match.

a'2=6(2) - 1    = 11

Hope this helps!
