Tyler spends a winter day recording the temperature once every three hours for science class. At 9 am, the temperature was -1.8°F. Between 9 am and noon, the temperature rose 5°F. Between noon and 3 pm, the temperature dropped 18.1°F. Between 3 pm and 6 pm, the temperature decreased by 9.9°F. What was the temperature at 6 pm?

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?
