In the spinner below, the large wedges are twice the size of the smaller ones. what is true about the probability of landing on 2 and the probability of landing on 3?

a. the probability of landing on 2 is half the probability of landing on 3.
b. the probabilities cannot be predicted.
c. the probabilities are equal.
d. the probability of landing on 2 is twice the probability of landing on 3.

The probability of landing on two is twice the probability of landing on 3.

Step-by-step explanation:

The reason for this is because the section 2 is twice the size of section 3 it means that the probability of landing on two is twice the probability of landing on number 3.

the range is 19

step-by-step explanation:

the range is biggest number minus the smallest, so in this case it would be

41 - 22 = 19

, 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
