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
Answer:
T = 9
Step-by-step explanation:
SAMDEB
1. Subtract 7 from both sides. 6T + 7 - 7 = 61 - 7
2. 6T = 54
3. Divide both sides by 6, to isolate T. 6T ÷ 6 = 54 ÷ 6
4. Therefore, T = 9
Answer:
48 is the sum of that question
