Answer:
5859375
Step-by-step explanation:
These are the terms of a geometric sequence with n th term
[tex]a_{n}[/tex] = [tex]a_{1}[/tex] [tex]r^{n-1}[/tex]
where r is the common ratio and [tex]a_{1}[/tex] the first term
here r = [tex]\frac{375}{75}[/tex] = [tex]\frac{75}{15}[/tex] = [tex]\frac{15}{3}[/tex] = 5 and [tex]a_{1}[/tex] = 3, hence
[tex]a_{10}[/tex] = 3 × [tex](5)^{9}[/tex] = 5859375
