36 because the rest are prime #'8
Choose D
Because negative times negative =positive
In the given question,the given explicit formula is

Which is of the form

So the constant difference is 7 here.
Now for the recursive formula
To find the next term, we need to add 7 to the current term, that is

So the correct option is B
If a bag of pumpkin seeds must weigh within 2.1 grams in order to be accepted, each bags must weigh between (400-2.1) grams and (400+2.1) grams. This means that if a bag weighs less than 397.9 grams (x<397.9) or more than 402.1 grams (x>402.1) it will be rejected. Therefore, 397.9>x>402.1 is the range of rejected bags.
