Part 1
- Pick any number for the first blank. This is the first term of the arithmetic sequence, $a_1$.
- Choose whether the time spent will increase or decrease as the week continues for the second blank
- For the third blank, choose by how many minutes the practice will increase or decrease. -The second and third blanks combine to give the common difference, $d$. (positive for increase, negative for decrease)

anonymous · Answer

Once you have $a_1$ and $d$ you can write the formula for the sequence and use it to find $a_7$, the time practiced on the 7th day

$a_n=a_1+d(n-1)$
