7) a

8) a, c, d

9) it is incorrect because he did not distribute the three to both terms. The correct work would be 3(4x+12) = 180 ; 12x+36 = 180 ; 12x = 144 ; x = 12

Find Sn for the given arithmetic series a1=-26 d=-9 n=24

ryzh [129]

Answer:

- 3108

Step-by-step explanation:

The sum to n terms of an arithmetic series is

$S_{n}$ = $\frac{n}{2}$ [ 2 $a_{1}$ + (n - 1)d ]

Substitute the given values into the formula

$S_{24}$ = $\frac{24}{2}$ [ (2 × - 26) + (23 × - 9) ]

= 12 ( - 52 - 207 )

= 12 × - 259 = - 3108
