Gabe Amodeo, a nuclear physicist, needs 60 liters of a 40% acid solution. He currently has a 30% solution and a 60% solution. How many liters of each does he need to make the needed 60 liters of 40% acid solution?

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?
