Question

http://gyazo.com/74699e458e644be253641e3c207354a2 Can someone help me with this. I've plugged in 1, 2, 3, and 4 but none work

Answer 1

@cwrw238

Answer 2

When will a term be negative?

Answer 3

If a negative is times a positive?

Answer 4

In the series, when do the terms turn negative?

Answer 5

Im not sure :/

Answer 6

Never. None of the terms is negative. If you continue the series in the pattern shown, no term will ever be negative. So which two answers can you eliminate?

Answer 7

A and B

Answer 8

Good. Now for what value of n is \(\large 1^{n-1} \) equal to anything other than 1?

Answer 9

When theres a higher number being plugged into n?

Answer 10

No. Every power of 1 is equal to 1. That should allow you to eliminate another answer.

Answer 11

Oh okay

Answer 12

C would be eliminated right?

Answer 13

No. Look at D. The only thing changing is the power on 1. But changing the power on 1 does not change the value because every power of 1 is equal to 1.

Answer 14

OHHHHHHHHHHHHHHHHHHHH

Answer 15

God I'm not to bright am I

Answer 16

Thank you

Answer 17

You can verify C by putting in n=1, 2, 3, 4....
