Find the fifth, ninth and hundredth term of the sequence. show your work!   -19, -22, -25, -28, find the fifth, ninth and hundredth term of the sequence. show your work! 4, 14, 24, 34, determine if the sequence is geometric. if it is, find the common ratio. show your work! -1, 6, -36, 216

For the first one, the pattern is subtracting 3 each time.
So the fifth term would be -28 - 3 which is -31 
The ninth term would be -31 - (3 x 4) = -31 - 12 = -43
The hundredth term would be -19 - (3 x 99) = -19  - 297 = -316

For the second one, the pattern is adding 10
The fifth term would be 34 + 10 = 44
The ninth term would be 44 + (10 x 4) = 44 + 40 = 84
The hundredth term would be 4 + (10 x 99) = 994

For the third one, a geometric sequence follows the formula A(n) = a*r^(n-1)
This would be a geometric sequence as it goes -6^n 

Omg that is a big question and weird words and i’m only 5
