What is the first term in a geometric sequence if the common ratio is −3 and the sum of the first five terms is 427?

So, we know that r = -3, and that the sum of the first 5 terms is 427 hmmmm





and surely you know how much that is.

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?
