Answer:
n = 200
Step-by-step explanation:
The n th term of an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 6 and d = 9, thus
= 6 + 9(n - 1) = 6 + 9n - 9 = 9n - 3
Now = 1797, so
9n - 3 = 1797 ( add 3 to both sides )
9n = 1800 ( divide both sides by 9 )
n = 200

- We use two identical copies of the same conversion factor to convert from square inches to square centimeters. This is the "multple conversion" your teacher is referring to.
- Think of "square inches", aka
, as "inches times inches". Or think of a 1 inch by 1 inch square that has an area of 1 square inch. The same applies for the square centimeter unit as well.
