nthterm of the sequence 1,2,3,5,7,9 what will be the formula for finding the nth term of a series in which the difference between the terms increase by 1 after every k elements. For example (for k = 3) : 1,2,3,5,7,9,12,15,18.. Themean of 1, 3, 5, 7, 9, 11, 13 is 7. We can easily solve this problem by following the given steps. Now, we know. Mean = Sum of all observations/total number of observations. Mean of the given data = 1+3+5+6+9+11+13/7 ( The total number of observations here is 7. Whatis the nth term of the arithmetic sequence 1,3,5,7,9,11? A n+1 B n−1 C 2n+1 D 2n−1 Easy Solution Verified by Toppr Correct option is D) Clearly, the difference of successive terms of above sequence is constant which is 2 So given sequence is in AP with first term 1 and common difference 2 Hence general term is, a n=a+(n−1)d=1+(n−1)2=2n−1 SDFjMto.
