A) Fill in the blanks to show what the next three numbers are in the following sequence. 28 , 37 , 46 , 55 , 64 ,
,
,

b) Is the sequence arithmetic, geometric or neither?

a) 73, 82, 91

b) arithmetic

Step-by-step explanation:

a) We add 9 after each term, making the common difference 9.

As such, 64 + 9 = 73

73 + 9 = 82

82 + 9 = 91

b) This sequence is arithmetic because it has a common difference, if it had a common ratio, it would be geometric.

a negative exponent is translated as follows:

so, we have

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol
