19, 998.
It is: 998*180 = 179640 degrees

Suppose the sum is SS = 100 + 101 + ... + 998 + 999 Also, writing it in reverse order gives S = 999 + 998 + ... + 101 + 100 so, adding the two together, 2S = 1099 + 1099 + ... + 1099 + 1099 where there are 900 such terms. So S = 1099*900/2 = 494550.
No. 998 is not evenly divisible by nine.
When you sum 998 with 1.

7903 - 4371 = 3532 637 + 998 = 1635 3532/1635 = 2.16 It is approximately twice as great.
The sum of the positive integers between 99 and 999 is 299500 Since a = 100, and d = 2 note that the last term will be 998 using nth tem of an Ap Un= a+(n-1)d 998= 100+ (n-1)2 Then 998- 100= (n- 1)2 = 898= (n-1)2 449= n-1 n= 450 Sum of the terms = n/2(2a+(n-1)d) 450/2(2(100) + 449*2) Ans= 247050 =
The sum of the first 1,000 counting numbers (which excludes zero) is 500,001.
Suppose the sum is SS = 100 + 101 + ... + 998 + 999 Also, writing it in reverse order gives S = 999 + 998 + ... + 101 + 100 so, adding the two together, 2S = 1099 + 1099 + ... + 1099 + 1099 where there are 900 such terms. So S = 1099*900/2 = 494550.
