Please help me with my question!!

Look at this pattern ; 1,4,9, number 10000 belongs in this pattern . what’s the place of this number?

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?

The track team ran a mile and a quarter during their practice how many kilometers did her team runs?
