Answer:
Step-by-step explanation:
1.5 , 3 , 4.5 , 6 ............
This is an arithmetic sequence. Each term is obtained by adding 1.5 to the previous term.
First term = 1.5
Common difference = second term - first term
= 3 - 1.5 = 1.5
Check:
Second term = 1.5 + 15 = 3
Third term = 3 + 1.5 = 4.5
Fourth term = 4.5 + 1.5 = 6
Answer:
Step-by-step explanation:
let n be the number
n+9
Answer:
B (pretty sure...its been a while)
Step-by-step explanation:
1. The '5x' cancels out since the top number is positive, and the bottom number is negative.
2. Subtract: '4y - 2y' = 2y
3. Subtract '25 - 3' = 22
4. So once you put the answers to part 2 and 3 below the line, you get...
2y = 22
