There are actually two series in the given series.Take the numbers alternately
One series --> 625 , 125 , 25, 5
Second series --> 5 , 25, ?
If we observe the 1st series --> 5⁴ , 5³ , 5² , 5¹
It is in decreasing order of power of 5
In 2nd series it is increasing orde rof power of 5
5¹, 5²,5³.........
So 5³ = 125
125 is the missing number.
