Answer 1

Answer:

(c) the common difference d = 2

Step-by-step explanation:

================

My dear friend, if you want to get the correct answer, PLEASE COPY the task precisely!!!

If $a_{8}$ = 17 and $a_{14}$ = - 29, then d = - $\frac{23}{3}$

From the choices you provide, there is no such an answer.

================

I assume that $a_{14}$ = 29

$a_{n}$ = $a_{1}$ + (n - 1)d

$a_{1}$ + 7d = 17  .......... (1)

$a_{1}$ + 13d = 29  ......... (2)

Subtract from (2) (1)

6d = 12 ===> d = 2
