METHOD - IWe can additionally use the (mean (average)) (=) (fracSum-of-all-ElementsNumber-of-Elements), inside we room asked to find the amount of the elementsHere,1. Number of elements (=) (200)2. Mean, in this instance is a equally spaced list (=) (fracFirst + Last2) (=) (frac1 + 2002) (=) (frac2012)3. Sum of the aspects (=) (frac2012) (*) (200) (=) (20,100)METHOD - IIWe can likewise directly apply the formula (fracn*(n + 1)2) were (n) stand for variety of elements. In this case (n) equals (200).(frac200 * (200 + 1)2 = frac200 * 2012 = 20,100)Ans. E_________________

**If a college student understands the principle "In an AP, typical = Median", one can reach the answer yes, really fast. Due to the fact that the inquiry in context asks around sum that the first 200 hopeful integers, just take 1st 199 confident integers. Because median of an initial 199 positive integers is 100, therefore, sum = number of terms x average = 199 x 100 = 19900. Now, include the staying 200 come it.19900 + 200 = 20100Hence, the price is E. _________________**

First ApproachSum of very first 100 confident integers = 5050. Now, 101 come 200, each term will be 100 an ext than a specific term in 1 come 100. Because that example, 101 is 100 more than 1, 102 is again 100 more than 2... And also so on till 200 is 100 much more than 100.... Thus, the amount of 101 to 200 will certainly be the amount of 1 to 100 + 100*100 = 5050 +10000 = 15050Sum of every 1 come 200 = 5050+15050 = 20,100. Second ApproachIt have the right to be taken that integers are consecutive and also thus question ideas AP series. It will be much better that college student recollect every the essential concepts and formulas related to the AP series. Use the formula because that the amount of the an initial positive n integers.1 + 2 + 3 + 4 + ... + n = (n)(n+1)/2Thus, 1+2+…+200 = 200(200+1)/2 = 20100_________________
