First you have to organize it like this
1 : 2 : 3 : 4
15 : 13: 11 : 9
If the sequence is decreasing then the nth term equation will start with a negative.try to see which will work -1,-2,-3,-4...
The answer is: x= -3n + 17
Tan=opposite over adjacent so the equation is tan=4/1 x=4

Step-by-step explanation:
S+24/7 = -2
7×{S +24/7} = -2×7
S+24 = -14
S+24-24 = -14-24
S = -38
