Answer:
5th term = 2*1st term + 3*2nd term
Step-by-step explanation:
z₁ : 1st term, z₂ : 2nd term
z₃ = z₁ + z₂
z₄ = z₃ + z₂ = z₁ + 2*z₂
z₅ = z₄ + z₃ = (z₁ + 2*z₂) + (z₁ + z₂) = 2*z₁ + 3*z₂
I think you are asking for 3 different ways of diving 100 pounds of potatoes into 5 and 2 pounds bags.
Alright:
- 5 two pounds bags and 18 five pounds ones
- 10 two pounds bags and 16 five ones
- 15 two pounds bags and 14 five pounds ones
Simplifying 6ab + 3ab - 7ab
so we can write it
6ab + 3ab - 7ab = 0 ( because there is nothing on right side )
9ab - 7ab = 0
2ab = 0
So the coefficient of ab is 2.
Correct option is C.
