Question

How do you write the first 5 terms of the sequence `An= 3n +1`?

Answer 1

The sequence is: 4,7,10,13,16,...

Explanation:

To calculate `m-th` term of a sequence you have to substitute `n` in the formula. For example:

`a_{color(red){1}}=3*color(red){1}+1=3+1=4`

`a_{color(red){2}}=3*color(red){2}+1=6+1=7`

and so on.
