Suppose that, without even reading the questions, you guess on all four questions of a true-or-false test. Compare the quantity in Column A with the quantity in Column B. Choose the best answer.
Column A
P(exactly one right
answer)
Column B
P (exactly one wrong
answer)
O The quantity in Column A is greater
O The quantity in Column B is greater.
O The two quantities are equal.
The relationship cannot be determined from the information given.

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.

, 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
