SAT Math 2.5 Algebra and Functions

This one is just a "fill in the missing numbers of the pattern" problem,

but, we have to figure out what the pattern actually is...

So the formula for the pattern is t sub n equals t sub n minus 1 squared.

Hmm, lot of variables to just say: "any term equals the term before it squared."

The first number is given.

All we have to do is find the next numbers in the pattern.

The first number, squared, should give us the second number of the pattern.

The square root of x squared equals x.

The second number squared equals the third number.

X squared equals...x squared.

And the third number squared equals the fourth number.

Remember your exponent rules here... when an exponent is being raised

to another power, multiply the two powers together.

So x squared squared equals x to the power of 2 times 2, which is x to the power of 4.

So D is the correct answer.

Man... we would kill it playing Simon...
