Answer:

Number of self-Help books sold = 252 books

Step-by-step explanation:

Total books sold last week = 1,125

Central angle for the Self-Help slice = 80.64°

Total angle in a circle = 360°

How many of the books sold were Self-Help books?

Number of self-Help books sold =

Central angle for the Self-Help slice / Total angle in a circle × total number of books sold

= 80.64° / 360° × 1,125

= 0.224 × 1,125

= 252

Number of self-Help books sold = 252 books

What is the 97th term of the arithmetic sequence -16,2,20

MAXImum [283]

Answer:

1712

Step-by-step explanation:

Given arithmetic sequence is: -16,2,20

Here, a = - 16, d = 2 - (-16) = 2+ 16 = 18

n = 97, $a_{97}=?$

$\because a_n = a + (n-1)d\\\\\therefore a_{97}= - 16 + (97-1)\times 18\\\\\therefore a_{97}= - 16 + 96\times 18\\\\\therefore a_{97}= - 16 + 1728\\\\\therefore a_{97}=1,712\\\\$
