Sequences & Series

Sequence and series are the basic topics in Arithmetic. An itemized collection of elements in which repetitions of any sort are allowed is known as a sequence, whereas a series is the sum of all elements. An arithmetic progression is one of the common examples of sequence and series.

● In short, a sequence is a list of items/objects which have been arranged in a sequential way.

● A series can be highly generalized as the sum of all the terms in a sequence. However, there has to be a definite relationship between all the terms of the sequence.

What Is Apple Cider Vinegar?

Apple cider vinegar (ACV) is a type of vinegar made with crushed fermented apples, yeast, and sugar. It's used as an ingredient in foods such as salad dressings, pickles, and marinades.

For many years, people have also used it as a home remedy for everything from fighting germs to preventing heartburn. More recently, research has shown that apple cider vinegar might have some real health benefits, such as helping reduce blood sugar levels and aid weight loss.

While there's not a lot of evidence for these benefits, ACV is generally harmless—as long as you use it correctly.
