If we increase q by 2, it means that q becomes q+2.
So, p will become

So, the new value for p is 6 more than the previous one.
The second exercise looks a bit odd: if the sequence started with -100, then it would be
-100, -97, -94, -91, -88,...
And every term would be 3 more than the previous one, so the next term would be -85, but this doesn't appear in your option.
Also, the fact that the sequence starts with positive 100 is quite strange, because it is unrelated to the rest of the sequence.
Are you sure that the exercise is written correct? Or are there any typos?
Shawna and her best friend Keisha together spend $ 138
<h3><u>
Solution:</u></h3>
Given that, Shawna and her best friend Keisha go shopping.
The function given for money each girl spent based on the number of hours they were shopping is:

<em><u>Find the amount of money that each girl spent</u></em>
For t = 2 hours

<em><u>Find the amount of money that they spend together</u></em>
Multiply by 2 the amount of money that each girl spent

Answer:
d) This is a completely randomized design with two explanatory variables (factors).
Step-by-step explanation:
Explanatory variables are independent variables.
In this case, I prepared two explanatory variables, which are : (i)30-second ad
(ii) 60-second ad,
Then, the explanatory variables were assigned to 4 treatment groups, and each variable is done once or thrice.
All subjects are assigned randomly to all treatment groups, with each treatment group seeing one. We can conclude that this is a completely randomized design with two explanatory variables.
