Answer:

[tex]a_{n}[/tex] = 18n + 26

Step-by-step explanation:

The n th term of an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 44 and d = 62 - 44 = 18 , thus

[tex]a_{n}[/tex] = 44 + 18(n - 1) = 44 + 18n - 18 = 18n + 26
