Answer:

9765625

Explanation:

There is a common ratio between consecutive terms , that is

r = 25 ÷ 5 = 125 ÷ 25 = 5

This indicates the sequence is geometric with n th term


a_(n) = a₁
r^(n-1)

where a₁ is the first term and r the common ratio

Here a₁ = 5 and r = 5 , then

a₁₀ = 5 ×
5^(9) = 5 × 1953125 = 9765625
