Considering the possibilities for each position:

For the first letter, it must be a consonant, so there are 4 options (B, C, D, and F).

For the second, third, and fourth letters: There are 7 letters remaining (A, C, D, E, F, G), and any of these letters can be chosen for each position. Therefore, there are 7 options for each of the three middle letters.

For the fifth letter, it must be a vowel, so there are 3 options (A, E, G).

To find the total number of words, we multiply the number of options for each position:

4 (\text{options for the first letter}) \times 7 (\text{options for the second letter} ) \times 7 (\text{options for the third letter}) \times 7 (\text{options for the fourth letter}) \times 3(\text{options for the fifth letter})= 5,880 .

Therefore, there are 5,880 words with five letters that start with a consonant and end with a vowel using the given letters.
