Final answer:
The Now-Next form for the sequence -3, -6, -9, -12 is -12, -15, -18, -21.
Step-by-step explanation:
To find the Now-Next form for the sequence -3, -6, -9, -12, we need to calculate the differences between consecutive terms. The difference is constant, so we subtract the common difference from each term to get the next term. In this case, the common difference is -3.
So, the Now-Next form for the sequence is -12, -15, -18, -21.
