Answer:
The next term is 42
Step-by-step explanation:
Let's use Arithmetic Progression
a₁ = - 3
a₂ = 12
a₃ = 27
Now,
The Formula of Common Difference d is
d = a₂ - a₁
= 12 - (-3)
= 12 + 3
d = 15
d = a₃ - a₂
= 27 - 12
d = 15
Here, the common difference is same
aₙ = aₙ₋₁ + d
a₄ = a₄₋₁ + 15
a₄ = a₃ + 15
a₄ = 27 + 15
a₄ = 42
So, The next term is 42

The final answer is x=12
So the ladder will reach 12 feet up
Simple. Just add/subtract each term. 4n-2n=2n. 8m+7m=15m.
This is very basic stuff.
X+2y=5
x = -2y+5
-2(-2y+5) - y = -4
4y - 10 -y = -4
3y - 10 = -4
3y = 6
y = 2
x + 2(2) = 5
x + 4 = 5
x= 1
Therefore, the coordinates are (1,2).
