Find the next two terms in the sequence. 9.8, 0.7, -8.4, -17.5, -35, -70 -26.6, - 35.7 26.6, 35.7 18.9, 28 find the exact value of the eighth term of the geometric sequence: 648, 216, 72, .30 8/27 8/2481 8/9 find the next three terms of the geometric sequence: -3, 6, -12, -36, 48, -60 -34, 58, -92 48, -96, 192 -48, 96, -192

The first one is arithmetic with CD = -9.1  so the answer is B

Third  one is D

Second question:

a1 = 648 and r = 1/3  so 8th term  = 648 * (1/3)^7  =  8/27

The first one subtracts 9.1 --> -26.6, -35.7
The second one subtracts 35 --> -105, -140
The third one subtracts 9.1 --> -44.8 , -53.9
The fourth one adds 9.1 --> 44.8 , 53.9
The fifth one adds 9.1 --> 37.1 , 46.2

I am sorry I do not have time to do the rest, but just find a pattern between the given terms and apply that to the next terms

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle
