The first term in an arithmetic sequence is 5. The third term in the sequence is -1. The tenth term in the sequence is -22. Xavier said that the recursive formula for this sequence could be described as, “to find the next term of the sequence, add -3 to the previous term.” Do you agree or disagree that this statement is equivalent to the explicit formula from question 18? Explain.

Recall that the owner of a local health food store recently started a new ad campaign to attract more business and wants to know if average daily sales have increased. historically average daily sales were approximately $2,700. the upper bound of the 95% range of likely sample means for this one-sided test is approximately $2,843.44. if the owner took a random sample of forty-five days and found that daily average sales were now $2,984, what can she conclude at the 95% confidence level?
