1.	If we add the first n odd numbers we get ______(a) n^2(b) 2n(c) 3n(d) nThe question was posed to me in a job interview.My enquiry is from Properties of Squares in portion Squares and Square Roots of Mathematics – Class 8
Answer» Correct CHOICE is (a) n^2 To explain: When we add FIRST n odd NUMBERS we get, n^2. For example: the first 5 odd numbers are 1, 3, 5, 7 and 9 When we add them, we get, 1+3+5+7+9+=25. We know that 25 is the square of number 5. HENCE, we find that when first n numbers are added we get n^2.
