Answer:

881

Step-by-step explanation:

Arithmetic sequences can be written as:

$a_n = a_1 + (n-1)d\\a_1 \: is \: 17\\a_n = 17 + (n-1)d\\$

The second term is 26,

$26 = 17 + (2-1)d\\9 = 1d\\d = 9\\a_n = 17 + (n-1)*9\\a_n = 17 + 9n - 9\\a_n = 8 + 9n$

So, the $97^t^h$ term is

$a_9_7 = 8 + 9(97)\\a_9_7 = 8 + 873\\a_9_7 = 881$
