 Arithmetic Sequence:  A sequence of numbers in which the difference between any two consecutive terms is the same.
Arithmetic sequences exist in real world situations whenever these is a constant difference with equal increments. For example, if you are shopping and buy tee-shirts at $6 each, the first one will cost $6, the second will be $12, the third will be $18, and so on. The arithmetic sequence, in this case, will be 6, 12, 18, 24, 30, 36,
