Would someone mind helping me with this quick precalc question? I have no idea how to solve this!
Find an equation for the nth term of the arithmetic sequence.
a19 = 58, a21 = 164
Here are my choices:
an = 896  53(n  2)
an = 896  53(n  1)
an = 896 + 53(n + 1)
an = 896  53(n + 1)

Best ResponseYou've already chosen the best response.1for option a) we test like: \(a_\color{red}{n}= 89653 (\color{red}{n}2)\) \(a_\color{red}{19} = 896 53(\color{red}{19}2)\) You calculate \( a_{19}=??\)

Best ResponseYou've already chosen the best response.0Oh! So a must not be the answer because a19 is supposed to equal 58

Best ResponseYou've already chosen the best response.1Yes, it is 5 for \(a_{19}\) of that formula while our \(a_{19} = 58\)

Best ResponseYou've already chosen the best response.1have to test \(a_{21}\) also, to make sure that you are not lucky when getting it.
