Enter the correct 4 digit code ( no spaces)

ABCD= 5934

Step-by-step explanation:

 5934

Step-by-step explanation:

To find A, add 3+2=5

To find B use the calculated 5 to get 5+4 =9

To find C do the reverse of adding: Subtract 4-1=3  Rewrite as 1+3=4

To find D do the reverse of adding: Subtract 9-5=4 Rewrite as 4+5=9

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.
