Nathan's Blog

I am just going to give a review for chapter 13 for this blog.

Section 1 dealt with sequences. An arithmetic sequence is when you add or subtract to get to the next number. A geometric sequence is when you multiply or divide to get to the next number.

Ex. 5,7,9,11.... This sequence is arithmetic because you added 2.

3,6,12,24.... This sequence is geometric because you multiplied by 2.

Now, on to limits. This was a very easy section to do.

1.) If the top exponent is equal to the bottom exponent, then you take the coefficients.
2.) If the top exponent is greater than the bottom exponent, the answer is +- infinite.
3.) If the top exponent is less than the bottom exponent, the answer is 0.

n^2/10n^3=0 (2 is less than 3)
2n^4/n^4=2 (same exponent; coefficient is 2/1)
5n^7/3n^2=Infinite (7 is greater than 2)

Now we are done with chapter 13. This chapter was easier than some of the previous ones.
