We have that
<span>n (n-1) -4
for n=1
a1=1*(1-1)-4------> a1=-4
for n=2
</span>a2=2*(2-1)-4------> a2=-2
for n=3
a3=3*(3-1)-4------> a3=2
for n=4
a4=4*(4-1)-4------> a4=8
the answer is
-4,-2, 2, 8
Answer:
the answer is 7
Step-by-step explanation:
angle 30°
x=14/2
x=7
24x+8x= 32x
32x-11x=21x
21x=-7-14
-7-14=-21
21x=-21
-1
that is not possible cause the first 2 indicate that the pattern is counting by 2s
