Make a conjecture about the next term in the sequence: 0.5, -1, 2, -4 *

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?

Iwould say 48 bc the line of x is the line of 6 so 6×6=48
