What is the recursive formula for this sequence? 24,20,16,12

the sequence first term is 24

a= 24

Common difference (d) = T2 - T1 = T3 - T2

d = 20-24 = 16 -20

d = -4

Formula for nth term

Tn = a + (n-1)d

Tn = 24 + (n -1)-4

Tn = 24 -4n + 4

Tn = 28 - 4n

= 28 - 4n

<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.

What is the completely factored form of 25x4 – 16y2?

jeyben [28]

Das is difference of 2 perfect squares
remember
a^2-b^2=(a-b)(a+b)

so
25x^4=(5x^2)^2
16y^2=(4y^2)

(5x^2)^2-(4y)^2=(5x^2-4y)(5x+4y)
cannot be factored further
