Answer:
9765625
Step-by-step 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
= a₁
where a₁ is the first term and r the common ratio
Here a₁ = 5 and r = 5 , then
a₁₀ = 5 × = 5 × 1953125 = 9765625
