Now change matrix b to a 3 x 3 matrix and enter these values for b:
b = 1.2 1.4 3.1
[2.2 1.1 5.6]
3.7 4.2 6.7
then select a • b to calculate the product:
77 39 −33
1.2 1.4 3.1
[2.2 1.1 5.6=c11 c12 c13]
3.7 4.2 6.7
c11 =
c12 =
c13 =

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.

4
