Assuming the sequence continues according to the same rule, what number appears in the 11th element?
To solve this problem, we'll follow these steps:
Now, let's work through each step:
Step 1: The given sequence starts with 2, 5, 8. We determine the pattern by finding the difference between consecutive terms:
and so the common difference () is 3.
This indicates it is an arithmetic sequence with and .
Step 2: Use the arithmetic sequence formula to find the 11th term :
Substitute the known values:\
Therefore, the 11th element in the sequence is , which corresponds to choice
