Solution:
The given letter series can be split into smaller groups as follows:
- ab_
- aa_
- caab_
- c_
- abb_
- c
To find the missing letters, we need to identify the pattern in each group.
In the first group, the second letter is 'b', which is the next letter in the alphabetical order after 'a'. Therefore, the missing letter should also be the next letter in the alphabetical order after 'a', i.e., 'b'.
In the second group, the third letter is 'a', which is the same as the first letter. Therefore, the missing letter should also be 'a'.
In the third group, the first two letters are 'ca', which are the last two letters of the previous group. Therefore, the missing letter should be 'a' followed by 'b', i.e., 'ab'.
In the fourth group, it is difficult to identify the pattern. However, we can observe that the fifth group starts with 'abb', which is the same as the last three letters of the previous group. Therefore, the missing letter should also be the same as the last letter of the previous group, i.e., 'b'.
In the fifth group, the third letter is 'b', which is the next letter in the alphabetical order after 'a'. Therefore, the missing letter should also be the next letter in the alphabetical order after 'a', i.e., 'b'.
Therefore, the completed letter series is:
abbaaccaabacbabbac
The given letter series can be split into smaller groups as follows:

In the fifth group, the third letter is 'b', which is the next letter in the alphabetical order after 'a'. Therefore, the missing letter should also be the next letter in the alphabetical order after 'a', i.e., 'b'.
Therefore, the completed letter series is:
