Final answer:
To find the 41st term of the arithmetic sequence starting with 11, 16, 21, use the formula for the nth term of an arithmetic sequence. The 41st term is calculated as 211.
Step-by-step explanation:
The student is asking for the 41st term in an arithmetic sequence. The given sequence is 11, 16, 21, which suggests a common difference of 5. To find the 41st term (a41) of an arithmetic sequence, you can use the formula: an = a1 + (n - 1)d, where 'a1' is the first term, 'd' is the common difference, and 'n' is the term number.
Applying this formula, we get: a41 = 11 + (41 - 1)×5 = 11 + 40×5 = 11 + 200 = 211. Therefore, the 41st term is 211.
