Given that XZ is a diameter of the circle and XZ perpendicular VW, VY congruent

SOLUTION:  

You need to walk through the proof step by step.

Look over what you are given and what you need to

prove. Here, you are given two congruent segments.

You need to find a way to relate the smaller segment

with the larger segments. Use the properties that you

have learned about congruent segments and

equivalent expression

Step-by-step explanation:

the answer

b. they are parallel and will never intersect.

, and

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
