Alimited-edition poster increases in value each year. after 1 year, the poster is worth $20.70. after 2 years, it is worth $23.81. which equation can be used to find the value, y, after x years? (round money values to the nearest penny.) y = 18(1.15)x y = 18(0.15)x y = 20.7(1.15)x y = 20.7(0.15)x

If the increase keeps a constant proportion, you can find the rate as 23.81/20.70 = 1.15

Then, after x years the value, y, can be found using y = 20.70 (1.15)^x.

 

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?
