Question

Write an explicit formula for the arithmetic sequence whose first term is a1=−12\displaystyle $$a_1$$ = -\frac{1}{2} and whose common difference is d=14\displaystyle d = \frac{1}{4}.

Accepted Answer

an=n−34\displaystyle a_n = \frac{n - 3}{4}

Answer

an=n−24{\displaystyle a_{n}=\frac{n-2}{4}}

Answer

an=n−14{\displaystyle a_{n}=\frac{n-1}{4}}

Answer

an=n−22{\displaystyle a_{n}=\frac{n-2}{2}}
