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
