Determine if the series is convergent or divergent 20-15+10-5....
Kazeer [188]

Answer:

Option b is correct.

The series 20-15+10-5....is Divergent

Step-by-step explanation:

Alternating series Test:

\sum_{n=1}^{\infty} (-1)^{n-1} (b_n) =b_1-b_2+b_3-........

b_n>0 satisfies:

  • b_{n+1} \leq b_n   for all n
  • \lim_{n\rightarrow \infty} b_n = 0

Then the series converges,

otherwise diverges.

Given the series: 20-15+10-5....

This is a alternating series:

\sum_{n=1}^{\infty} (-1)^{n-1} (20-5(n-1))

b_n = (20-5(n-1))

b_{n+1} = (20-5(n+1-1)) = (20-5n)

using the alternating series test;

b_{n+1} \leq b_n  for all n

\lim_{n\rightarrow \infty} b_n = \lim_{n\rightarrow \infty} (20-5(n-1)) = -\infty

⇒ the series diverges.

therefore, the given series i,e 20-15+10-5.... is divergent.

Find the value of the variables in the parallelogram
zavuch27 [327]

Answer:

A

Step-by-step explanation:

y = 180 - 100 - 38 (angle sum of triangle is 180 degrees)

= 42 degrees

x = 38 degrees (alternate angles on || lines)

z = 100 degrees (opposite angles on parallelogram are equal)
