Answer:
The two numbers following 1,-2,3,-4,5... are -6 and 7.
Step-by-step explanation:
index: 1 2 3 4 5 ....
value: 1 -2 3 -4 5
Let the index be n. Then the first term is a(1), the secon is a(2), and so on.
a(2) = 2*(-1)^(2-1) = 2*(-1) = -2 (correct)
a(3) = 3*(-1)^(3-1) = 3*(-1)^2 = 3 (correct)
a(4) = 4*(-1)^(4-1) = 4*(-1)^3 = -4 (correct)
So the general formula for a(n) is: a(n)=n(-1)^(n-1)
Thus,
a(5) = 5(-1)^4 = 5
a(6) = 6(-1)^5 = -6
a(7) = 7(-1)^6 = 7
The "next two numbers in the pattern" are -6 and 7. The first 7 numbers are
1,-2,3,-4,5, -6, 7

Answer:
∠K = ∠M = 55°
Step-by-step explanation:
The two marked angles are opposite the sides marked as congruent. That means the angles are congruent, so we have ...
4x -1 = 2x +27
2x = 28 . . . . . . . . add 1-2x to both sides
x = 14
4x -1 = 4(14) -1 = 55
The measures of the angles are ...
∠K = ∠M = 55°
