Q. Which recursive formula can be used to define this sequence for

n > 1

\newline

-4, 1, 6, 11, 16, 21, \ldots

\newline

Choices:

\newline

(A)

a_n = 11a_{n-1}

\newline

(B)

a_n = a_{n-1} + a_{n-1} + 5

\newline

(C)

a_n = a_{n-1} + 5

\newline

(D)

a_n = \frac{1}{5}a_{n-1}

Given Sequence Type: We have: $-4, 1, 6, 11, 16, 21, \ldots$ $\newline$ Is the given sequence geometric or arithmetic? $\newline$ The difference between consecutive terms is the same. $\newline$ The given sequence is arithmetic.
Find Common Difference: $-4, 1, 6, 11, 16, 21, \ldots$ $\newline$ Find the common difference, $d$ . $\newline$ Two consecutive terms are $-4$ and $1$ . $\newline$ $1 - (-4) = 5$ $\newline$ Common difference ( $d$ ): $5$
