Select the missing number to complete the given sequence.

5, 25, 125, 625, ?

The correct option is 3125.

To find the missing number in the sequence, let us analyze the pattern between consecutive numbers:

$5\times 5=25$

$25\times 5=125$

$125\times 5=625$

We can observe that each term in the sequence is obtained by multiplying the previous term by 5. Alternatively, the sequence represents consecutive powers of 5 ($5^1=5$, $5^2=25$, $5^3=125$, $5^4=625$).

Following this multiplication pattern, the missing fifth term is obtained by multiplying the fourth term (625) by 5:

$625\times 5=3125$

Therefore, the missing number to complete the sequence is 3125.
