1 2 3 4 5 6 To 100
One way to make it accurate is by adding seven plus and minus signs like so.
1 2 3 4 5 6 to 100. A better way to solve this is to make pairs. If we have 100 numbers 1 100 then we clearly have 100 items. So adding the first and last numbers off we get 101 each. Notice that 1 100 is 101 2 99 is 101 3 98 101 in that order.
Now for yr 7 or 8 the method is to find a pattern. 1 99 100 2 98 100 3 97 100 49 51 100 so you ve made 100 49 times so that s 4900. 4900 100 50 5050. 1 2 3 4 5 6 7 8 9 100.
Let s count from 1 to 100 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47. For every big number there s a small number on the other end. Let s look at a small set. When i tried my 100 day pushup challenge based on the same method i needed to start at around 10 cuz doing just 1 and then 2 and then 3 was just too boring slow for me and eventually i gave up.
This equation is incomplete. So let s figure out the sum. An interactive math lesson about whole numbers to 100. Though in this case starting at 100 pushups a day would probably kill me.
To get the average notice that the numbers are all equally distributed.
