 Hi and welcome to the session. Let us just cast a following question. The question says find the indicated terms. In each of the sequences and exercises 7 to 10 whose innate terms are, tenth part is a n is equal to n into n minus 2 upon n plus 3 and we have to find a 20. Let's now begin with the solution. Given innate term is a n is equal to n into n minus 2 upon n plus 3, since we need to find a 20 therefore we will put n as 20 in the innate term. By substituting n as 20 in the innate term we get a 20 is equal to 20 into 20 minus 2 upon 20 plus 3. Now this is equal to 20 into 8 sorry 18 upon 23 and this is equal to 360 upon 23 hence the required 20th term that is a 20 is equal to 360 by 23. This is our required answer. So this completes the session. Bye and take care.
