C

D

Answer
409
Explanation
Solution
In a sequence of consecutive odd numbers, the average is the middle number. With 101 numbers, the middle number is 303. To find the largest number in this sequence, add 50 to 303 (since there are 50 numbers on each side of the middle). Thus, the largest number is 303 + 50× 2 = 409.
