To find the 77th term of an arithmetic sequence, we use the formula for the $n$th term of an arithmetic sequence:

$a_n = a_1 + (n - 1) \cdot d$

Where:

• $a_n$ is the $n$th term,
• $a_1$ is the first term,
• $d$ is the common difference,
• $n$ is the term number.

Given:

• $a_1 = 8$ (the first term),
• $d = 26 - 8 = 18$ (the common difference),
• $n = 77$ (the term number we want to find).

Substituting the values into the formula:

$a_{77} = 8 + (77 - 1) \cdot 18$

$a_{77} = 8 + 76 \cdot 18$

$a_{77} = 8 + 1368$

$a_{77} = 1376$

So, the 77th term of the arithmetic sequence is 1376.
