Question

For each sequence,find the first 4 terms and the 10th term.
a)3n+4
b)4n-5​

Answer 1

i know a good trick on how to do this.

Explanation:

The number 4 is apart of the sequence, but it has been taken away by 3.

3+4=7. Since it was taken away by 3, we have to add 7 by 3 to get 9. So on and so forth.
