Answer:
see explanation
Step-by-step explanation:
These are the terms of a geometric sequence with n th term
[tex]a_{n}[/tex] = a[tex](r)^{n-1}[/tex]
Where a is the first term and r the common ratio
r = [tex]\frac{10}{5}[/tex] = [tex]\frac{20}{10}[/tex] = [tex]\frac{40}{20}[/tex] = 2
and a = 5, hence explicit equation is
[tex]a_{n}[/tex] = 5[tex](2)^{n-1}[/tex]
Answer:
5(2^x-1)
Step-by-step explanation:
uh just take the first number and multiply it with the common difference
