Question 25

1, 5, 25, 125, ? , ? , ?

Solution

we have been give a series as 1, 5, 25, 125, ? , ? , ?

here we can see that every term is a power of 5

1 = 5 ^ 0

5 = 5 ^ 1

25 = 5 ^ 2

125 = 5 ^ 3

so the next term will also be power of 5 and the terms are 5 ^ 4, 5 ^ 5 , 5^6 i,e 625, 3125, 15625
