The first four terms of a sequence are, 9,2,-5,-12. State the pattern of the sequence using algebraic expressions.

Step-by-step explanation:

Given,

9,2,-5,-12

Now,

t1=9

t2=9-7=2

t3=2-7=-5

t4=-5-7=-12

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s
