Find the difference between consecutive terms. If all of them in the sequence have the same difference, then it's an arithmetic sequence. The fourth answer, for example, is not an arithmetic sequence. The difference of 14 and 4 is 10 since 14-4=10. The difference of 24 and 14 is also 10. But the difference between 32 and 24 is 8. Since 8 isn't the same as the other differences, it's not an arithmetic sequence. That should be enough for you to determine which of the remaining sequences is arithmetic.
Find to LCM of 8 and 18 to compare times
Mary: 4*9laps/8*9min
36 laps/ 72 mins
Nicole: 12*4laps/18*4 mins
48 laps/ 72 mins
Nicole runs more laps in the same amount of time as Mary
Therefore, Nicole runs faster
Answer:-3
Step-by-step explanation:
Answer:
2
Step-by-step explanation:
We are given:
t = -11
u = 11
v = 1
Plug in the values to (tv-u) / tv:
((-11)(1) - 11) / (-11)1
(-11-11) / -11
-22 / -11
= 2
