Answer:
A) The sequence is geometric because the sequence is increasing by a factor of 2 being multiplied to each term, when ascending from left to right.
B) 
C) 
Step-by-step explanation:
The sequence is multiplying each term by a factor of 2.
5*2=10
10*2=20
20*2=40
R=I+6 S=4R I
I+(I+6)+4(I+6)=126
Basic algebra (I dont know how to show it) leaves you with: 6I = 90, divide both sides by 6 and I=15
Answer: 6.9
Step-by-step explanation: Find the number in the tenth place 8
and look one place to the right for the rounding digit 7. Round up if this number is greater than or equal to 5 and round down if it is less than 5.
6.9
(b) , because if you expand 3(n+6), it is
(3×n)+(3×6) = 3n+18
