Final answer:

The 43rd term of the arithmetic sequence -124, -122, -120,... is -40.

Step-by-step explanation:

The given sequence is -124, -122, -120,... which is an arithmetic sequence with a common difference of 2. To find the 43rd term, we can use the formula:

nth term = first term + (n-1) * common difference

Plugging in the values, we have:
43rd term = -124 + (43-1) * 2
43rd term = -124 + 42 * 2
43rd term = -124 + 84
43rd term = -40

Therefore, the 43rd term of the sequence is -40.
