I hope this gets you started in the right direction.
Answer:
x = 4
Step-by-step explanation:
a = i-2j
b = 2i-xj
1 = k•2
-2 = k•(-x)
=> 1/2 = k
=> (-2)/(-x) = k
=> 1/2 = (-2)/(-x) => 1/2 = 2/x => x = 4

Answer:

Step-by-step explanation:

Answer:
The rule is x₁ = 2 x₂ = x₁ * 2 x₃ = x₂ + 3 x₄ = x₃ * 2 x₅ = x₄ + 3 ...
Step-by-step explanation:
Unable to use a single equation to define this sequence
The rule is x₁ = 2 x₂ = x₁ * 2 x₃ = x₂ + 3 x₄ = x₃ * 2 x₅ = x₄ + 3 ...
Multiply 2 then Plus 3 then multiply 2 then plus 3 ......
