Tyrone's age is 2 years less than 4 times his younger sister's age. if his younger sister's age is b years, which of the following expressions best shows tyrone's age?
4b
b − 2
2b − 4
4b − 2

Four times his sister's age would be 4b.  His age is two years less, so we need to subtract 2.

Put together, this is 4b - 2.

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?
