Q. Marie sent pieces of mail in October, pieces of mail in November, pieces of mail in December, and pieces of mail in January. What kind of sequence is this?Choices:(A) arithmetic(B) geometric(C) both(D) neither
- List Mail Sent: List the number of pieces of mail sent by Marie in each month.October: November: December: January: Sequence:
- Check Arithmetic: Determine if the sequence is arithmetic by checking if the differences between consecutive terms are equal.Difference between November and October: Difference between December and November: Difference between January and December: Check if the differences are equal: The differences are not equal, so the sequence is not arithmetic.
- Check Geometric: Determine if the sequence is geometric by checking if the ratios between consecutive terms are equal.Ratio of November to October: Ratio of December to November: Ratio of January to December: Check if the ratios are equal: The ratios are equal, so the sequence is geometric.
