Question

4, 12, 20, ... Find the 41st term.

Answer 1

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!
