The even numbers are given by tn = 2n, giving {2, 4, 6, ...} for n = 1, 2, 3, ...
The median of an even number of data items is the mean of the middle two, which is the mean of the (100 / 2) = 50th and (100 / 2) + 1 = 51st even numbers, ie:
median = mean(2 x 50, 2 x 51)
= (2 x 50 + 2 x 51) / 2
= 2 x (50 + 51) / 2
= 50 + 51
= 101
8 numbers, so the median is the mean average of the 4th and 5th numbers. 4th number is 86 5th number is 86 median = (86 + 86) ÷ 2 = 86.
The median of those numbers is 90.
90.5 is the median, as it is the number that is halfway between the two, or half of the total of the two numbers.
The average of the first n even numbers is n+1, so 101.The average of the first n even numbers is n+1, so 101.The average of the first n even numbers is n+1, so 101.The average of the first n even numbers is n+1, so 101.
When put into size order, the middle two numbers are 87 and 94. So the median is (87 + 94)/2 = 90.5
The first 100 even numbers are: 2 468101214161820222426283032343638404244464850525456586062646668707274767880828486889092949698100102104106108110112114116118120122124126128130132134136138140142144146148150152154156158160162164166168170172174176178180182184186188190192194196198200.
The first 100 whole, even numbers are: 2468101214161820222426283032343638404244464850525456586062646668707274767880828486889092949698100102104106108110112114116118120122124126128130132134136138140142144146148150152154156158160162164166168170172174176178180182184186188190192194196198200.
The sum of the first 100 positive even numbers is 10,100.
The sum of the first 100 even numbers is 10,100
The sum of all the first 100 even numbers is 10,100.
8 numbers, so the median is the mean average of the 4th and 5th numbers. 4th number is 86 5th number is 86 median = (86 + 86) ÷ 2 = 86.
The median of those numbers is 90.
There are 10 square numbers from 1 to 100, so the median is the mean average of the middle two - the 5th and 6th square numbers = (25 + 36) ÷ 2 = 30.5
(1, 5, 97, 99, 100, 100) The mode is 100. The median is 98. The mean is 67.
50 half of 100 is 50
90.5 is the median, as it is the number that is halfway between the two, or half of the total of the two numbers.
The sum of the first 100 positive even numbers can be calculated using the formula for the sum of an arithmetic series: n*(first term + last term)/2. In this case, the first term is 2, the last term is 200, and n is 100. Therefore, the sum is 10,100.
