Now we just need to do some simple arithmetic. You will see that we will get the same number every time because the small number increases by 9 and the big number decreases by 9.ģ. ![]() We get this number 225 times because after are used we go to the next numbers. Next we add the smallest and biggest numbers together. ![]() (Wow what are the chances of getting such a nice number□)Ģ. This gives us 449 but we must remember that at the beginning we took out the 11, so we have 450 total numbers. Then we get 4041, Next we divide by 9 because that is the increments that this is increasing by. So because we start at 11 we subtract 11 from 4052. Find the number of total numbers in the equation. In order to solve this series we have to make pairs.ġ. ![]()
