Evaluate 2/3 + 1/3 + 1/6 + … THIS IS CONTINUOUS. It is NOT as simple as 2/3 + 1/3 + 1/6.
Vlada [557]

a=\dfrac{2}{3}\\r=\dfrac{1}{2}

The sum exists if |r|

\left|\dfrac{1}{2}\right| therefore the sum exists

\displaystyle\\\sum_{k=0}^{\infty}ar^k=\dfrac{a}{1-r}

\dfrac{2}{3}+\dfrac{1}{3}+\dfrac{1}{6}+\ldots=\dfrac{\dfrac{2}{3}}{1-\dfrac{1}{2}}=\dfrac{\dfrac{2}{3}}{\dfrac{1}{2}}=\dfrac{2}{3}\cdot 2=\dfrac{4}{3}

Answer:

m = {-6, -4}

Step-by-step explanation:

<u><em>Subproblem 1:</em></u>

Set the factor '(6 + m)' equal to zero and attempt to solve:

Simplifying

6 + m = 0

Solving

6 + m = 0

Move all terms containing m to the left, all other terms to the right.

Add '-6' to each side of the equation.

6 + -6 + m = 0 + -6

Combine like terms: 6 + -6 = 0

0 + m = 0 + -6

m = 0 + -6

Combine like terms: 0 + -6 = -6

m = -6

Simplifying

m = -6

<u><em>Subproblem 2:</em></u>

Set the factor '(4 + m)' equal to zero and attempt to solve:

Simplifying

4 + m = 0

Solving

4 + m = 0

Move all terms containing m to the left, all other terms to the right.

Add '-4' to each side of the equation.

4 + -4 + m = 0 + -4

Combine like terms: 4 + -4 = 0

0 + m = 0 + -4

m = 0 + -4

Combine like terms: 0 + -4 = -4

m = -4

Simplifying

m = -4
