Find the 16th term of the arithmetic sequence whose common difference is d=9 and whose first term is a, = 1.

136

Step-by-step explanation:

Common difference of 9 means that each term is 9 apart from each other:

1 + 9 = 10 + 9 = 19 + 9 = 28 ...

We can then find the nth term

The difference is 9 → 9n

The 0th term is 1 - 9 = -8

nth term = 9n - 8

Finally plug in (substitute) 16 for n

9(16) - 8 = 144 - 8 = 136

The 16th term is 136
