What are the next two terms of the following arithmetic sequence - 3, 1, 5, 9, ...

13 and 17.

Each time 4 is being added, so do 9+4=13, then 13+4=17.

The 5th number is 13 and the 6th number is 17.

Step-by-step explanation:

For more difficult question, you have to use this way. the rule for arithmetic sequence is An=a1+d (n-1)

So all you have to do is replace the things.

So, you are looking for the 5th spot, the first term is - 3, and the difference is 4, replace the n with the 5.

A5=-3+4 (5-1)

5-1 is 4

4*4 = 16

A5 = -3+16

16-3=13

A5=13

Do the same for A6, just instead of the "5's" put "6's".

A6=-3+4 (6-1)

6-1 + 5

5*4 = 20

20-3=17

A6 = 17
