Question

Find the first 5 terms of the sequence given the nth term? 1.an=n+4 2.an=2n-1 3.an=12-3n Thanks

Answer 1

See explanation.

Explanation:

To find `n-th` term of a sequence you have to substitute `n` in the formula. As an example I will calculate the first term of each sequence.

Examples:

1. `a_color(red)(1)=color(red)(1)+4=5`

2. `a_color(red)(1)=2*color(red)(1)-3=-1`

3. `a_color(red)(1)=12-3*color(red)(1)=9`
