Answer:
Estimation is finding a number that is close enough to the right answer. ... 550 + 248: 50+48 is nearly 100 so an estimate is 500+200 +100 = 800.
Hey there Hopire :)
To solve this, we'll use the slope given two points formula. Here it is:
y2-y1/x2-x1
Plug in the values.
6-2/9-7 =
4/2 =
2
Therefore, the slope is two, meaning 2/1 because slope is rise/run. That means that for every two you go up, you go one to the right because it's a positive slope- left for negatives.
Hope this helped!
14n-8 is how you find the answer, and the next term is 62
Answer:
5050
Step-by-step explanation:
Gauss has derived a formula to solve addition of arithmatic series to find the sum of the numbers from 1 to 100 as follows:
1 + 2 + 3 + 4 + … + 98 + 99 + 100
First he has splitted the numbers into two groups (1 to 50 and 51 to 100), then add these together vertically to get a sum of 101.
1 + 2 + 3 + 4 + 5 + … + 48 + 49 + 50
100 + 99 + 98 + 97 + 96 + … + 53 + 52 + 51
1 + 100 = 101
2 + 99 = 101
3 + 98 = 101

:
48 + 53 = 101
49 + 52 = 101
50 + 51 = 101
It was realized by him that final total will be fifty times of 101 means:
50(101) = 5050.
Based on this, Gauss has derived formula as:
The sequence of numbers (1, 2, 3, … , 100) is arithmetic and we are looking for the sum of this series of sequence. As per Gauss, the special formula derived by him can be used to find the sum of this series:
S is the sum of the series and n is the number of terms in the series, in present case, from 1 to 100, Hence
As per the Gauss formula, the sum of numbers from 1 to 100 will be 5050.
Answer : 5050
