1 answer:
Answer:
<em>x, 2x+1, 4x+3, 8x+7</em>
Step-by-step explanation:
If we call the first term <em>x</em>, then the subsequent term is <em>2x+1</em>. Then, the next term is <em>2(2x+1)+1=4x+2+1=4x+3</em>. Then, the fourth term is <em>2(4x+3)+1=8x+6+1=8x+7</em>.
As a matter of fact, the <em>n</em>th term is given by for starting term <em>x</em>.

Like terms must have the same variables and those variables must have the same powers.
and
are like terms, because they both have
and they both have
.
and
are NOT like terms, because the powers no longer match.
In your example, do you have the same variables and do the variables have the same powers in both expressions?
