Answer:
a1 = 17
an = 4n + 13
Step-by-step explanation:
a1
a1 is the first term of the sequence, which is 17.
an
the difference is 4 for each number.
Using formula
an = a1 + (n - 1)d
an = the formula of an itself
d = difference
a1 = first term
So,
an = a1 + (n - 1)d
an = 17 + (n - 1)4
an = 17 + 4n - 4
an = 4n + 13
So the an = 4n + 13
