Final answer:
To find the next two terms in the sequence, we subtract 30 from the last term in the sequence.
Step-by-step explanation:
To find the next two terms in the sequence (40, 10, -20, -50, ...), we can observe that each term is obtained by subtracting 30 from the previous term. So, to find the next term, we subtract 30 from the last term given (-50). This gives us the next term as -80. Finally, subtracting 30 from -80 gives us the last term in the sequence as -110.
