A) the arithmetic sequence given is 1, 11, 21, 31, 41, and we can find the nth term using the formula for the nth term of an arithmetic sequence, which is given by: an =a1 (n−1)⋅d where a1 is the first term, n is the term number, and d is the common difference. Solves your equations step by step and shows the work! this calculator will solve your problems. The logic follows here is: as, all the given options are the prime numbers except 21. hence, "21" is the correct answer. download solution pdf share on whatsapp. Therefore, 10 n 1 is the general term of series. option a : if we put n = 1, 2, 3, 4, 5 in 10 n 9 , we get series 1, 11, 21, 31 . so, which is not true. option b : if we put n = 1, 2, 3, 4, 5 in 10 n 1 , we get series 9, 19, 29, 39, so, which is not true.
