QuestionWrite an expression to describe the sequence below. Use $n$ to represent the position of a term in the sequence, where $n=1$ for the first term. $$\begin{array}{l} -6,-12,-18,-24, \ldots \\ a_{n}=\square \end{array}$$

Studdy Solution
Substitute the values of $a_1$ and $d$ into the general formula.
$$a_n = -6 + (n-1)(-6)$$
Simplify the expression: $$a_n = -6 - 6(n-1)$$ $$a_n = -6 - 6n + 6$$ $$a_n = -6n$$
The general term of the sequence is: $$a_n = -6n$$
