Answer:
a)+3
b)7n-11
Step-by-step explanation:
for a
you must subtract -9 and -6 and the answer would be +3 same for the rest of the pattern so the answer is +3.
there is no need to find the multiple and difference as it goes in pattern of 3's in the 3 times table format.
for b
find the difference between -4 and -11 which is -7, same for the rest of the sequence but it does not follow the 7 times table format so we must find the difference between 7 and -4 which is -11 so...
the rule would be 7n-11
hope this helps btw. make sure to double check
