Answer: The answer is 3n + 2
Step-by-step explanation: You will have to combine like terms:
=−n + −4 + 4n + 6
=(−n + 4n) + (−4 + 6)
=3n + 2
Answer b - Line BC... The adjacent line is the one directly across from the letter in question.
Which sequence below represents an exponential sequence? A) {2, 6, 10, 14, 18,...} B) {3, 5, 9, 16, 24,...} C) {4, 8, 24, 96,...

Answer:d
Step-by-step explanation:
Clearly from observation option D is the exponential sequence
256,64,16,4 is decreasing exponential function
for other option they simply follow an AP
2,6,10,14,18
common difference d=4
18x + 20 + x = 10x -3
Combine like terms
19x + 20 = 10x -3
Subtract 20 to both sides because whatever you do on one side you have to do it on the other side:
19x = 10x -23
Subtract 10x
9x = -23
Divide 9 to isolate x:
x = -23/9
Simplify to get a mixed number:
x = -2 5/9
