b. Reasoning In finding the values of x and y in OKLMN, does it matter which variable you solve for first? Explain. M + 8 2x y + 2 Р y + 10 K N A. Yes; it is only possible to write an equation for x. Once you have found x, you can solve for y. B. Yes; it is only possible to write an equation for y. Once you have found y, you can solve for X. C. No; solutions to a system of equations do not depend on the method used to solve it. D. No; since x and y must be equal, you can solve for either variable first.

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

, and for

central angle of a triangle has the same measure as its intercepted arc.
