Question

A list of numbers ordered from least value to greatest value is shown. 18/5 , 3.71, ? , square root of 17. One number is missing. eighteen over five. three point seven one. blank. square root of seventeen Which number could be the missing number?

Answer 1

To find the missing number in a list (18/5, 3.71, ?, √17), convert the known values to the same format. The missing number should be greater than 3.71 and less than √17 (approximately 4.12), such as 3.8 or 3.9.

Step-by-step explanation:

The student has asked which number could be the missing number in a list that is ordered from least to greatest: 18/5, 3.71, ?, √17. To find the missing number, we need to compare the given numbers after converting them to a common format (either decimals or fractions).

First, we convert 18/5 to a decimal, which is 3.6. Next, we observe that √17 is approximately 4.12 when rounded to two decimal places (since √16 is 4 and √17 will be slightly more). Now we have 3.6, 3.71, ?, 4.12 in the list. The missing number must be greater than 3.71 and less than 4.12.

A possible missing number that fits between 3.71 and the square root of 17 could be 3.8 or 3.9, as these are between the two given decimals.
