Final answer:

To find the 70th term of an arithmetic sequence, use the formula Term_n = a + (n-1)d, where a is the first term, n is the term number, and d is the common difference.

Step-by-step explanation:

To find the 70th term of an arithmetic sequence, you can use the formula:

Termn = a + (n-1)d

where a represents the first term, n represents the term number, and d represents the common difference.

In this case, the first term is 18 and the common difference is 16 (since each term is increasing by 16).

So, for the 70th term:

Term70 = 18 + (70-1)16 = 18 + 69*16 = 18 + 1104 = 1122
