18-2(3+4) how do i solve this problem?

You have to distribute the -2 to the equation in the parenthesis.

Then you need to combine like terms

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?
