Explanation

The first letter can be chosen in 26 ways. Similarly, second letter can be chosen in 26 ways. Hence, the first 2 letters can be chosen in 26 × 26 ways. Also, the third letter can be chosen in 26 ways. Hence, the first 3 letters can be chosen in 26 × 26 × 26 ways. But the fourth letter should be similar to second letter. This can be done in just 1 way. Similarly, fifth letter should be similar to first letter. This can be done only in 1 way. Hence, number of words possible = 26 × 26 × 26 × 1 × 1 = 17576
