Question

205,201,197,... \text{Find the 48th term.} Find the 48th term.\

Answer 1

17

Explanation:

You need to use the formula for Arithmetic Sequences.

`a_(n)=a_(1)+(n-1)d`

You need to plug in the value for
`a_(1)` which is just the first value in your sequence. As well as
`n` which is the term your looking for, in this case it's 48. Lastly
`d` which is the amount that the pattern is increasing or decreasing by. If the sequence is increasing then the
`d` is positive but if the sequence is decreasing then the
`d\\` is negative.
