Finally get to swoop in and answer!

Each new value is 1 plus twice the previous value.

First value is 1. Then,

1 plus twice 1 = 3, the second value.

Second value is 3

1 plus twice 3 = 7, so

Third value is 7

and so on (this is merely a check)

<u>Answer: </u>

The population of a city has decreased by 38% since it was last measured. If the current population is 27,900 .Previous population of city was 45000.

<u> Solution: </u>

Given that current population of city is 27900.

Also, population of a city has decreased by 38% since it was last measured.

Let assume that population of city when it was last measured = x

Decreased of 38% means x-38% of x . we can write this as,

$=x-\frac{38}{100} \times x$

$=\frac{100 x-38 x}{100}$

$=\frac{62 x}{100}=\frac{31 x}{50}$

So current population is $\frac{31 x}{50}$

Equating above expression to the given value of current population, we get

$\frac{31 x}{50}=27900$

$x=\frac{27900 \times 50}{31}$

x=45000

Hence previous population of city was 45000.
