Iam a number rounding to the nearest thousand makes me 1000.all my digits are even their sum is 12 they are in order from greatest to least and no digit is repeated what is the number

The answer is: 642

Step-by-step explanation:

Add 6 + 4 + 2 = 12

You only have 2, 4, 6, 8 to work with. 642 rounded to the nearest thousand is 1,000. The order of 642 is from greatest to least and no number repeats.

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.

true !
