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

a_n = a + (n-1)d

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

Substituting the given values, we have:

a_11 = 4 + (11-1)(-1)

a_11 = 4 - 10

a_11 = -6

Therefore, the 11th term of the sequence is -6.

To find the 30th term, we use the same formula:

a_30 = 4 + (30-1)(-1)

a_30 = 4 - 29

a_30 = -25

However, the question is asking for the opposite of the 30th term, so the answer is:

-(-25) = 25

And 25 is not given, so the closest option is:

-30
