Students in Mrs. Portock's class were trying to write an expression that represents the total number of cubes for any term number, n, for the sequence below. Diego raised his hand to get help from Mrs. Portock. He had the table following written on his paper: Term # (n) # of cubes 1 1 2 4 3 7 4 10 Diego said he recognized the pattern of adding 3 more cubes every time, but needed help writing an expression using n. Of the following, what is the best possible teacher response?

Re-write the number of cubes as an expression showing the amount of cubes being added every time. (Ex: 1+3 instead of 4 cubes, 1+3+3 instead of 7 cubes, etc.)

Mr. Miller gives students the table above and tells them about a commissioned sales person. He asks students to fill in the missing boxes and write a summary of how the number of sales, x, is related to the monthly salary, y. Which of the following best demonstrates how x and y are related?

Mr. White displayed 3 sequences on his whiteboard during math class: 20,10,5,0,−2.5,...20,10,5,0,−2.5,... 324,108,36,12,4,...324,108,36,12,4,... −6,1,8,15,22,...−6,1,8,15,22,... He asked his students to pick one of the sequences, determine if it was arithmetic or geometric, and explain their reasoning for their answer. Which student answer correctly identifies the sequence and has a sufficient explanation?

"−6,1,8,15,22,...−6,1,8,15,22,... is an arithmetic sequence because if you add 77 to each term, you get the value of the next term in the sequence. When you have a common difference, the sequence is arithmetic."

What is the next shape in this pattern?
