1st Year Math Chapter 6 Sequence and Series MCQs

If your search is to get the 1st Year Math Chapter 6 Sequence and Series MCQs With Answers then you are in the right place. This chapter is very important in terms of the entry test. But here we are providing the important MCQs of this chapter. A sequence is used to represent ordered lists of numbers. Through these, you will be able to have a grip on the concepts including sequences and types of sequences. After this, we have two different terms Arithmetic Progression and Arithmetic Mean, Harmonic Progression and Harmonic mean. Next, we have the concept of series, Geometric Progression, Geometric Mean, infinite geometric series, and finally the relationship between arithmetic, geometric, and Harmonic means. So, let’s check the important MCQs of this chapter below.
