Pleaa helll jack father 4 times old his son five years later both age diffrence is 10 find both age.

Step-by-step explanation:

Let Jack's present age be x

Hence, his fathers present age=4x

Jacks age after 5 years= (x+5)

Jacks Fathers age after 5 years= (4x+5)

We know.. that the difference between their ages fives years later is 10.. hence

4x+5-(x+5)=10

4x+5-x-5=10

3x = 10

x= 3.3 years old...

Hence,

Jacks present age = 3.3 years

Fathers present age= 13.2 years...

Hope it helps .. I know that the answer comes in decimals... but the questions' like that..

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.
