Part 1: Create a scenario for an arithmetic sequence. For example, Jasmine practices the piano for ______ minutes on Monday. Every day she ___________ her practice time by _________. If she continues this pattern, how many minutes will she practice on the 7th day? Be sure to fill in the blanks with the words that will create an arithmetic sequence. Use your scenario to write the function for the 7th term in your sequence using sequence notation. I need help learning how to solve this problem I don't get it just step by step on how

    The first thing you have to do is pick numbers for the blanks.

    ok. so now you can write the formula for the sequence. \[a_n=a_1+d(n-1)\] \(a_1\)=10 because that was how much she practiced on the first day d = 5 because that's how much it increases each day. Plug them in to get the formula for you specific numbers

    an = a1 + d(n-1) an = 10 + 5(n - 1) an = 10 + 5n - 5 an = 5n + 5 I think you may have added wrong somewhere

    Now for the last step you plug in 7 for n to find \(a_7\). \[a_7=5(7)+5\]
