A sum of rupees 100 is invested at 8% per annum Simple Interset. Calculate the interest at the end of $1_{st}, 2_{nd}, 3_{rd} ....$ years. Is the sequence of interest an Arithmetic Progression. Find the interest at the end of 30 years.
Hint: Arithmetic Progression follows the rule of $a_n = a+(n-1)d$ where $n$ the term of the AP
My Problem: I am having problem in creating the Arithmetic Progression in this Question, because In this I am totally confused about concept.
