Answer:

2520 sequences are possible in the word 'pioneer' if the letters can be repeated.

Step-by-step explanation:

Total number of letters in the word 'pioneer' = 7

Number of times E is repeated = 2

So, the number of sequences possible are  $=\frac{7!}{2!}$

                                                                        $=\frac{5040}{2}$

                                                                        $=2520$

Therefore, there are 2520 possible sequences that can be made from the word 'pioneer' if the letters of the word can be repeated.
