Ellen sent 1 e-mail on Wednesday, 1 e-mail on Thursday, 2 e-mails on Friday, and 3 e-mails on Saturday. What kind of sequence is this?

1 answer

The sequence of e-mails sent by Ellen over the days is: 1 (Wednesday), 1 (Thursday), 2 (Friday), and 3 (Saturday).

If we look at the number of e-mails sent each day, we have the following numbers:

  • Wednesday: 1
  • Thursday: 1
  • Friday: 2
  • Saturday: 3

We can represent the sequence as: 1, 1, 2, 3.

To analyze the pattern in the sequence:

  • From Wednesday to Thursday, the count stays the same (1 to 1).
  • From Thursday to Friday, the count increases by 1 (1 to 2).
  • From Friday to Saturday, the count increases by 1 again (2 to 3).

The sequence modifies the initial fixed count on Wednesday and Thursday, and then begins to follow a pattern of increasing by 1 each day after that.

This can be seen as a partially defined sequence where the initial values are constant, and then it takes on a linear growth pattern. Beyond that, the numbers follow a type of Fibonacci-like growth, where each number is the sum of the two previous ones after a certain point.

Overall, this sequence can be categorized as a simple arithmetic and Fibonacci-related sequence.
