Find the interest on 40,000,00 for 2years at 20% per anum compound interest

Iwould say they are complementary because that’s the division of a 90 degree angle and it’s split between the middle of them

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?
