Answer:

[tex]\frac{5}{8}[/tex]

Step-by-step explanation:

The n th term of a geometric sequence is

[tex]a_{n}[/tex] = a₁[tex](r)^{n-1}[/tex]

where a₁ is the first term and r the common ratio

here a₁ = 10 and r = [tex]\frac{1}{2}[/tex], thus

[tex]a_{5}[/tex] = 10 × [tex](1/2)^{4}[/tex] = 10 × [tex]\frac{1}{16}[/tex] = [tex]\frac{5}{8}[/tex]
