Answer:
The equation is
x =
Step-by-step explanation:
The Equation is formed from two sides equal to each other
- In the algebraic statement "is" means equal
- In the algebraic statement "of" means times (×)
∵ One eighth means 
∴ Negative one eighth means 
→ Assume that the number is x
∵ "of" means times
∴ Negative one eighth of a number =
× (x)
∴ Negative one eighth of a number =
x
∵ Negative one eighth of a number is 
→ "is" means equal, so the left side is
x and the right side is 
∴
x =
⇒ Equation
∴ The equation is
x =
Answer:
an = 1/2 (n) (n+1)
Step-by-step explanation:
1,3,6,10,.........
3-1=2
6-3=3
Each term is different so there is no common difference. It is not an arithmetic sequence
3/1=3
6/3 =2
Each term is different so there is no common ratio. It is not a geometric sequence
1 3 6 10
+2 +3 +4
a1 = 1
a2 = 3
a3 = 6 = 2*3
a4 = 10 = 2*5

The first step to apply using the elimination method is by multiplying the whole value of equation 1 by 3/2.
