A box contains 7 red pencils and 5 blue pencils. Without looking, Kamden reaches into the box and chooses 2 pencils, one at a time, without replacement. What is the probability that Kamden chooses 2 blue pencils? A. 25/132 В. 25/144 C. 5/33 D. 5/36​

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.

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
