Best Answer

the series of odd numbers from 1 to 99 :1 3 5 7 9.....99

SUM OF THE SERIES:

It is a geometric progression with a=1 and l=99 and common difference (d)=2.

let 99 be the nth term of the sequence

so, 99=1+(n-1)d

99=1+(n-1)2

solving this we get n =50.

SUM=(n/2)(a+l)

=(50/2)(1+99)

=(25)(100)

=2500.

What is the difference between the sum of all even numbers and odd numbers from 25 to 100?

The sum of the even numbers is (26 + 28 + ... + 100); The sum of the odd numbers is (25 + 27 + ... + 99) Their difference is: (26 + 28 + ... + 100) - (25 + 27 + ... + 99) = (26 - 25) + (28 - 27) + ... + (100 - 99) = 1 + 1 + ... + 1 There are (100 - 26) ÷ 2 + 1 = 38 terms above which are all 1; their sum is 38 x 1 = 38. So the difference of the sum of all even numbers and all odd numbers 25-100 is 38.

What is the percent of numbers whose digets add up to an odd number between one and one hundred?

Since we are talking for the sum of digits, then we are talking about 2-digit numbers between 1 and 100, which are 90 numbers (10 to 99). From these numbers only half of them satisfy the above condition, that is 45 numbers. So 50% of 2-digit numbers between 1 and 100 have an odd sum of their digits.
