Show all work. find the missing terms of the arithmetic sequence... , 4, ?, ?, ?, 120, ...
denis23 [38]

Answer:

  • -25, 4, 33, 62, 91, 120, ...

Step-by-step explanation:

<h3>Given</h3>

<u>The arithmetic sequence</u>

  • .. , 4, ?, ?, ?, 120, ...
<h3>To find:</h3>
  • Missing terms
<h3>Solution</h3>

<u>Let the first term a₁ = x, and common difference = d then we have:</u>

  • a₁ = x
  • a₂ = x + d = 4
  • ...
  • a₆ = x + 5d = 120

<u>The difference of the 6th and  2nd terms:</u>

  • a₆ - a₂ =
  • a + 5d - x - d = 120 - 4
  • 4d = 116
  • d = 116/4
  • d = 29

<u>Then we get the first term and other missing terms:</u>

  • x = 4 - 29 = -25
  • a₁ = -25

-25, 4, 4+29 = 33, 33+29 = 62, 62 + 29= 91, 91+29 = 120, ...

Tank 1 initially contains 50 gals of water with 10 oz of salt in it, while tank 2 initially contains 20 gals of water with 15 oz
Naddik [55]
\dfrac{\mathrm dx_1}{\mathrm dt}=\dfrac{2\text{ oz}}{1\text{ gal}}\dfrac{5\text{ gal}}{1\text{ min}}-\dfrac{x_1(t)\text{ oz}}{50\text{ gal}}\dfrac{5\text{ gal}}{1\text{ min}}
\dfrac{\mathrm dx_2}{\mathrm dt}=\dfrac{x_1(t)\text{ oz}}{50\text{ gal}}\dfrac{5\text{ gal}}{1\text{ min}}-\dfrac{x_2(t)\text{ oz}}{20\text{ gal}}\dfrac{5\text{ gal}}{1\text{ min}}

\implies\begin{cases}\dfrac{\mathrm dx_1}{\mathrm dt}=10-\dfrac1{10}x_1\\\\\dfrac{\mathrm dx_2}{\mathrm dt}=\dfrac1{10}x_1-\dfrac14x_2\\\\x_1(0)=10\\\\x_2(0)=15\end{cases}
