PI / 9

or

π/9

or

C

Step-by-step explanation:

√9/3 = 1

2π = 6.28

Answer has to be 1 < or > 6.28

A = 3.14

B = 3

C = 0.349

D = 1.09

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
