Hey there!
2x + 7 = 27
2x = 20
x = 10
3x + 1 = 28
3x = 27
x = 9
The values for both of these equations are 9 and 10; therefore, the answers are not equivalent.
I hope this helps!
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
You have to add all the common terms together.
The statement is a conditional statement.
