Question

What is the 6th value in the sequence with the explicit formula a n equals -2 and -14?

Answer 1

Since the explicit formula of the sequence is

`a_n=-2n-14`

Where n is the position of any term

We need to find the sixth term, which means

n = 6

Substitute n by 6 in the formula above

`\begin{gathered} a_6=-2(6)-14 \\ a_6=-12-14 \\ a_6=-26 \end{gathered}`

The sixth term is -26

The answer is B (2nd answer)
