 Hi, and welcome to our session. Let us discuss the following question. The question says, find the sum to indicated number of terms in each of the geometric progression in exercises 7 to 10. 10th part is x to the power 3, x to the power 5, x to the power 7, so on, tell n terms if x is not equal to plus minus 1. Let's now begin with the solution. Given gp is x to the power 3, x to the power 5, x to the power 7, and so on, up to n terms. Now here, the first term, that is, a is equal to x to the power 3, and the common ratio, that is, r is equal to x to the power 5 upon x to the power 3, and this is equal to x squared. We know that sum to n terms of the gp is given by a into 1 minus r to the power n upon 1 minus r. Now here, a is equal to x cubed, and r is x squared. So we have x squared to the power n upon 1 minus x squared. Hence, the required sum is x cubed into 1 minus x to the power 2n upon 1 minus x squared. This is our required answer. So this completes the session. Bye, and take care.
