The question is incomplete. To provide a meaningful answer, we need more information. A more complete question would be: "What are the first five terms of an arithmetic sequence if the sum of the first five terms is 145 and the common difference is 4?"

According to the reference, for an arithmetic sequence where the sum of the first 5 terms is 145 and the common difference is 4:

  • The third term is 29.
  • The five terms are 21, 25, 29, 33, and 37 respectively.

Therefore, the sequence is:

Term Value
1st 21
2nd 25
3rd 29
4th 33
5th 37

The sum of these terms is 21 + 25 + 29 + 33 + 37 = 145, confirming the given information.
