An arithmetic sequence can be expressed as explicitly or recursively
The explicit formula of the sequence is
The recursive formula is given as:
Substitute 2 for n in
This gives
Calculate the common difference (d)
The explicit formula is then calculated as:
This gives
Expand
Hence, the explicit formula of the sequence is

Answer:
Area ~= 52.4 m^2
OR (see image why)
Area ~= 52.3 m^2
Step-by-step explanation:
Use A = pi•r^2 to find the area of the whole circle. For a sector, times that by degrees/360.
Your problem has a 60° sector. 60/360 is 1/6.
Use either, 60/360 or 1/6 times 100pi.
If you use the pi button on the calculator the answer is .1 different than if you use 3.14 for pi in your calculation. The pi button answer is more accurate. See image.
