SolutionGiven: 1, 3, 5, 7, 9, 11 Note: 1+2= 3 3+2= 5 5+2= 7 7+2= 9 9+2= 11 Thus, every successive number is formed by adding 2 to the previous number. ∴ The next number can be obtained by adding 2 to the last given number, which is 11. ∴ Next number = 11 + 2 = 13 Suggest Corrections 0 Similar questions Q. Numberof subsets of A = {1,2,3,,8,9} such that the maximum is in B = {1,3,5,7,9} The answer that you've gotten can't possibly be correct; after all, there are only 29 = 512 TOTAL subsets of {1,2,,9}. So, there's some definite over-counting happening here. QuestionThe value of 1+3+5+7+9+.+25 is: A 196 B 625 C 225 D 169 Easy Solution Verified by Toppr Correct option is D) We take the first term a=1, last term l=25, common difference d=2 and the number of terms =n. Then, since it is an A.P. series, l=a+(n−1)d n= dl−a+1 = 225−1+1 = 225−1+2 = 225+1 = 226 =13 Let S n be the sum of n=13 terms .
