Altogether then, the new balance will be:Ī_2 = 9750 - 251.25 = 9498.75īut now in order to automate the process, let’s write everything in terms of I_n and A_n. That would leave 300-48.75=251.25 for paying off the loan. To compute the balance after the second month, we repeat the same steps. By convention, we write A_0 = 10,\!000 for the initial amount of the loan (let’s not worry about the dollar signs going forward). Therefore out of the first $300, only $250 will go towards paying off the loan. et I_n stand for the interest payment in month n. Each month, the bank charges 0.5% interest (6\% \div 12), or as a decimal: 0.005. First of all, the bank will tack on interest. Let’s work out the first month carefully. That is, we will examine the sequence of balances. However we can still answer the questions by finding out exactly what is still left to pay after each month. To answer these questions quickly, we would have to know about certain loan formulas. How long will it take to pay off the loan? How much interest will you end up paying? Suppose that the monthly payments were fixed at $300 by the lender. When the loan is in repayment, it will accrue 6% annual interest, compounded each month. So any time you have data arranged in a list, you may require methods from sequences and series to analyze the data.įor example, suppose you take out a small student loan for $10,000. Partial sum of the series worksheets require students to determine the n th partial sum of the series, find the n th term of the series and are categorized based on the difficulty level.A sequence is simply a list of numbers, and a series is the sum of a list of numbers. These recursive sequence worksheets concentrate on the idea of finding the recursive formula for the given sequences and ascertain the sequence from the implicit formula provided. This batch of general series includes exercises like rewrite each series as an expanded sum, rewrite each series using sigma notation, evaluate the series and more. This array of worksheets includes finding the explicit formula, finding the missing terms and much more. Learn to distinguish whether the sequence is arithmetic or geometric. This collection of special series worksheets centralizes the concept of determining the sum of the series related to natural numbers and finding n th term for special series and much more! Evaluate the sums of the infinite series. Get ample practice in the concept of infinite geometric series and learn to identify whether the series converges or diverges.
