#### Transcript of 8.2 Arithmetic Sequences and Partial Sums

a = dn + c n n term th common difference c = a - d 1 Recursion Formula a = a + d n + 1 n Now, you can find any term, provided you know the term before it. a and d both mean the same
thing as before n or (a - d = c) 1 a = a + (n - 1)d n 1 S = (a + a ) n n n 2 1 For the sum of a finite arithmetic sequence, Arithmetic Sequence a sequence where the difference between consecutive terms is the same EX: 1, 3, 5, 7, 9, 11 difference between consecutive terms is 2 d = 2 c = a - d
c = 1 - 2
c = -1 a = dn + c
a = 2*1 - 1
a = 2 - 1
a = 1 1 1 1 1
