The sum of 23 consecutive integers is 2323. What is the largest of these 23 integers?

1 answer:

6 0

Sum of consecutive integers = n*(n+1) / 2
2,323 = (n^2 +n)/2
4,646 = n^2 + n
n^2 + n -4,646 =0
n = 67.663 which is NOT an integer
Do you have the problem typed correctly?

Answer:

Step-by-step explanation:

You don't add the days to 350 to get the total miles and you don't add the time to 1400 miles. By having 350d the answer would be what times 350=1400 which is why that one is correct. (D= 4)
