Calculate the Tenth Term in the Quadratic Sequence 2n²

To solve this problem, we'll determine the tenth term of the sequence based on the formula $2n^2$.

• Step 1: Recognize that the sequence is defined by $2n^2$ for any term $n$.
• Step 2: To find the tenth term, substitute $n = 10$ into the formula:

$2n^2 = 2(10)^2$

• Step 3: Calculate the square of 10:

$(10)^2 = 100$

• Step 4: Multiply by 2 to find the sequence value at that position:

$2 \times 100 = 200$

Therefore, the tenth term in the sequence is $200$.

The correct answer choice is: $200$.
