First one is arithmetic sequence in disguise
an=a1+d(n-1)
a1=first term
d=common differce
n=which term
so
first erm is 4
common difference is 9-4=5
an=4+5(n-1)
when n=10
4+5(10-1)
4+5(9)
4+45
49
B
3.5, to 6.5, 9.5
aritmetic, increase by 3, first term is 3.5
an=3.5+3(n-1)
10th term
3.5+3(10-1)
3.5+3(9)
3.5+27
30.5
A is49
B is 30.5
A is answer
an=a1+d(n-1)
115+(-8)(14-1)
115-8(13)
115-104
11
answer is B
an=a1+d(n-1)
45+(-3)(10-1)
45-3(9)
45-27

The table shown is giving the probabilities of a positive response for two government programs from the citizens in eight cities.This question is asking for the positive response that can be obtained from Chicago for program 1 and 2. Then, you just need to fill the value inside the table. The chance that a positive response obtained from Chicago for program 1 would be 65.90%. The chance that a positive response obtained from Chicago for program 2 would be 87.50%
30 divided by 6=5
