What is the sequence technique of this number sequence 3 20 78 334 1696 ?

polet [3.4K]

3×2+14=20
20×3+18=78
78×4+22=334
334×5+26=1696
1696×6+30=10206
Hence, the question mark should be replaced by 10206

vova2212 [387]

W= 7

38=2w+2(12)
/
38=2w + 24
-24 -24

14=2w
divid by 2 divid by 2

X^2+4x-1/(x+2)^2=0 solve for x

dalvyx [7]

<span>x^2+4x-1/(x+2)^2=0
x^2 + 4x - 1 = 0
</span>
$\frac{x^2+10x-7}{x^2+10x+25} =0\\x^2+10x-7=0\\x= \frac{-b\pm\sqrt{b^2-4ac}}{2a}$ ;
where a = 1, b = 4 and c = -1

$x=\frac{-4\pm\sqrt{4^2-(4\times1\times(-1)}}{2\times1}\\=\frac{-4\pm\sqrt{16+4}}{2}=\frac{-4\pm\sqrt{20}}{2}\\=\frac{-4\pm\sqrt{4\times5}}{2}=\frac{-4\pm2\sqrt{5}}{2}=-2\pm\sqrt{5}\\=-2+\sqrt{5}
 \ or \ -2-\sqrt{5}\\x=0.24 \ or \ x = -4.24$

9y – 2 + y= 5y + 10

RideAnS [48]

Answer:

y=2.4

Step-by-step explanation:

9y-2+y=5y+10

(combine like terms)

10y-2=5y+10

(subtract 5y from both sides)

5y-2=10

(add 2 to both sides)

5y=12

(divide both sides by 5)

y=2.4
