Answer:

-496

Explanation:

The direct formula for the nth term of an arithmetic sequence is given by the formula:


x_n=a\cdot d(n-1)

Where a is the initial term, d is the common ratio, and n is the nth term.

Let's find a and d.

From the sequence, we can see that the initial term or a is 26.

Also, each subsequent term is 9 less than the previous term. In other words, our common ratio is -9.

Therefore, our direct formula is:


x_n=26-9(n-1)

To find the 59th term, substitute 59 for n:


x_(59)=26-9(59-1)

Subtract:


x_(59)=26-9(58)

Multiply:


x_(59)=26-522

Subtract:


x_(59)=-496

So, the 59th term is -496.

And we're done!
