    Answer:

    a_{n} = 6n + 1

    Step-by-step explanation:

    This is an arithmetic sequence with nth term

    a_{n} = a₁ + (n – 1)d

    where a₁ is the first term and d the common difference

    Here a₁ = 13 – 6 = 7 and d = 6 , then

    a_{n} = 7 + 6(n – 1) = 7 + 6n – 6 = 6n + 1

    Answer:

    the first few terms would be

    7, 13, 19, 25, 31

    nth term = 7 + 6(n+1)

    nth term = 7+ 6n + 6

    nth term = 6n + 13
