I think the definition of your sequence is u(n) = 3n - 2 .
That little set of parentheses makes it SO much
easier to read and understand.
To find u(any number) just write the number in place of 'n' .
u(27) = 3(27) - 2
= 81 - 2
= 79 .
The answer to 33 is 3. The answer to 37 is 9.
As go up the number sequence it is just the number added to get the new number plus 1. For example, since 2+3=5, 5+3=8+1=9
Answers are B, C, and D
If Q = 33, then the two slopes are both 33. As long as the y intercepts are different, then the two lines will be parallel leading to no intersections. No intersections means no solutions.
Note: Choice A leads to infinitely many solutions as we'll have identical copies of the same expression on each side (33x+25 = 33x+25). This is why we can rule choice A out.
Answer:
the second number is 4
Step-by-step explanation:
13+x=17
x=4
