If 20 is 40% of a value, what is that value?

I think it's 8, because you turn 40% into a decimal, which is .4, then we multiply .4 and 20. Finally, we get 8

20 is 40 %
to get from 40 % to 100% you multiply by 2.5
20 times 2.5 is 50
50 is 100%

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?
