an is the nth term of the sequence. When writing the general expression for an arithmetic sequence, you will not actually find a value for this. It will be part of your formula much in the same way x’s and y’s are part of algebraic equations.
a1 is the first term in the sequence. To find the explicit formula, you will need to be given (or use computations to...

...Freedom of Expression
There are some issues and problems that are very hard to solve. Freedom of expression is one of them. Its hardship springs from the ambiguity of the term freedom itself. Philosophers always ponder on the question as to whether freedom has its own bounds, or it referres to the absence of any kind of restrictions. There are some people asserting that people can express themselves however they want, and all kinds of...

...TRANSITION EXPRESSION
A Transitional Expression is a Transitional Phrase or a Conjunctive Adverb.
Transitional expressions help your reader to understand how you have organized your material, making it easier for them to move from one point to the next in your writing. Use Transitional expressions to: add ideas, emphasize ideas, illustrate ideas, compare/contrast ideas, show cause and effect, place ideas in time, and summarize ideas....
