• This sequence alternates between two patterns:
-Pattern 1: Starts with 5 and multiplies each subsequent number by 5 (5, 25, 125, 625)
-Pattern 2: Starts with an unknown number and repeats it (?, 25, 5)

• To find the missing number, we need to continue Pattern 2:
-The second number in Pattern 2 is 25.
-The third number in Pattern 2 is 5, which is 25 divided by 5.
-Following this logic, the first number in Pattern 2 should be 25 multiplied by 5, which is 125.
