4, 12, 20, ... Find the 41st term.
1 answer:
Answer:
324
Step-by-step explanation:
All you're simply doing is adding 8 to each number up until the 41st term OR an easier way, using the arithmetic sequence formula as shown below in the red box:
an is the term you want to find, in this case: the 41st term.
a1 is the first term in the list of ordered numbers
n is the term position, in this case, the same as an
d is the difference whether if it's adding or subtracting.
Now match the numbers in the formula and solve using PEMDAS from left to right!
