$T_{\ \textless \ -5,-3\ \textgreater \ }$ (ABC) means that the triangle is moving five units to the left and three units down
$T_{\ \textless \ -4,-2\ \textgreater \ }$ (ABC) means that the triangle is moving four units to the left and two units down

The triangle is moving a total nine units down and five units left

$T_{\ \textless \ -9,-5\ \textgreater \ }$ (ABC) is your final answer

PLEASE HELP!!!!! 3, 8, 13, 18, 23, ....<br><br> The recursive formula for this sequence is:

rodikova [14]

Answer:

a₈ = 37

Step-by-step explanation:

The given arithmetic sequence is: 3, 8, 13, 18, 23, . . .

The recursive formula for the sequence is: $a_n = a_{n - 1} + 5$

Here, $a_n$ represents the $n^{th}$ of the sequence.

And, $a_{n - 1}$ represents the $(n - 1)^{th}$ of the sequence.

'+5' denotes that '5' is added to the $(n - 1)^{th}$ term to get the $n^{th}$ term. In other words, the difference between two consecutive numbers in the sequence is 5.
