.Adam is 3 times as old as his sister Naya , in 4 years he will be twice as old as Naya , how old are Adam and Naya now ?

Step-by-step explanation:

The answer is

If naya is 4 years old then 3 times Adam age is 12

After 4 years naya is 8 years old and Adam is 16

We can check it because twice of 8 is 16

So now Adam is 12 years and Naya is 4 years old

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.

x-3y=4
