The correct answer for the first question is 23.To find the 7th term in the sequence , we can observe that the sequence is an arithmetic sequence with a common difference of 3. To find the 7th term, we can use the formula for the nth term of an arithmetic sequence: where is the nth term, is the first term, is the term number, and is the common difference.In this case, , , and . Plugging these values into the formula, we get: Therefore, the 7th term in the sequence is 20.The correct answer for the second question is 2.To evaluate when , we can substitute into the expression: Therefore, the value of when is 2.
