Question

if an-2=3n-11 find the nth term of the sequence​

Answer 1

Given t n =3n−1

To find the series, we will plug in numbers in the above expression.

For n = 1, 3n - 1 = 2

n = 2, 3n - 1 = 5

n = 3, 3n - 1 = 8

So, the sequence we get is 2, 5, 8, 11, .....

Answer 2

Answer:

-3

Step-by-step explanation:

-2+11=3n

-9=3n

-9/3=n

-3=n
