Answer:

[tex]a_{n}[/tex] = 10n - 5

Step-by-step explanation:

There is a common difference d between consecutive terms, that is

d = 15 - 5 = 25 - 15 = 10

This indicates the sequence is arithmetic with n th term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 5 and d = 10 , then

[tex]a_{n}[/tex] = 5 + 10(n - 1) = 5 + 10n - 10 = 10n - 5
