Extra Practice

My partner and I did an arithmetic sequence. The first four terms were: { 5, 2, -1, -4, ... } Find the tenth term.

Take the following into consideration:
Arithmeticc Sequence: The difference between any two consecutive terms is a constant.
Tn = T1 + (n - 1)(d)
Geometric Sequence: The ratio of any two consecutive terms is a constant.
Tn = T1( r^ (n - 1) )

I'de be glad to help anyone who doesn't understand.
Also, for extra practice Mr. A assigned Pgs. 473- 475 # 1-9 odd , 17-41 odd



Answer: Tn = 5+ (n- 1) (-3)
T10 = 5 + (10 - 1 (-3)
T10 = - 22
