Select the correct answer.
Emanuel is writing a novel. He writes 10 pages on the first day. Every day after that, Emanuel writes 16 more pages. Let y represent the total number of pages Emanuel writes after x days.
Which type of sequence does this situation represent?
A.The situation represents an arithmetic sequence because the successive y-values have a common difference of 16.
B.The situation represents a geomètric séquence because the successive y-values have a common ratio of 16.
C.The situation represents a geometric sequence because the successive y-values have a common ratio of 6.
D.The situation represents an arithmetic sequence because the successive y-values have a common difference of 6.
