Question

small town whose population was 18,395 ten years ago, has lost 270 inhabitants each year since then. what is the present population of small town?​

Answer 1

Answer:

15965

Step-by-step explanation:

a=18395

d= -270 (lost inhabitants every year)

n=10

tn=?

We know that,

tn= a+(n-1)×d

=18395+(10-1)×(-270)

=18395+9×(-270)

= 18395 -2430

=15965

Hence,the present population of small town is 15965.
