Answer:
Option b is correct.
The series 20-15+10-5....is Divergent
Step-by-step explanation:
Alternating series Test:

satisfies:
for all n
Then the series converges,
otherwise diverges.
Given the series: 20-15+10-5....
This is a alternating series:



using the alternating series test;
for all n

⇒ the series diverges.
therefore, the given series i,e 20-15+10-5.... is divergent.
Answer:
Six
Step-by-step explanation:
There are six equilateral triangles in a regular hexagon.
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)
