Week 1-My Arthmetic Sequence

Posted on by

In this week, we have learned about sequence and series which basically is finding a pattern with common difference with before and after numbers. For example,

  1. t_1=3
  2. t_2=-1
  3. t_3=-5
  4. t_4=-9
  5. t_5=-13

We can know from here that the common difference is -4 and we can know that the first number which is t_1 is 3.

Sum of all 50 numbers S_{50} would be 4850 as t_{50} is -193 and when we apply n=50, t_{50} which is -193 and t_1 which is 3, into Sn=\frac{n}{2}({t_1}+{t_n}) , S_{50} would be equavalent to 4850

It is important to have no calculation mistake in this chapter as it might affect greatly on our resultant value
