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?
Answer:
1st choice
Step-by-step explanation:
Temp at noon was -0.6. It increases 1.2 until 3.
-0.6+1.2
gets colder 0.4, then 0.6.
-0.6+1.2-0.4-0.6
the only correct way to put this equation as one of the other answers is by putting it as -0.6+1.2+(-0.4)+(-0.6)
hope that helped!
