Which of the following terms would not be in the series generated by the expression: 5

Signma symbol (k^2-5k+2)

k=2

the choices are 2, -2, 4 or -4If you could even just provide a starting point- we are just learning this and I'm not doing too great right now-thank you but I'm trying

**Julia**, Monday, December 5, 2011 at 12:18pmthe 5 should be on top then the signma symbol in middle and the k=2 on the bottom with the equation (k^2 -5k+2) to the right of all of it

**Reiny**, Monday, December 5, 2011 at 12:27pmIt simply means subbing in k=2, k=3 ... k=5 into the expression and adding up the results

that is.

= (2^2 - 5(2) + 2) + (3^2 - 5(3) + 2) + ... + (5^2 - 5(5) + 2)

= -4 + (-4) + (-2) + 2

I can see why you would be confused, since none of your choices are NOT a term generated by the expression.

Misprint in the question?

Question is faulty?

**Julia**, Monday, December 5, 2011 at 12:38pmNo the way I typed is is the way it is written--

5 on top, sigma symbol in middle and k=2 on bottom with the equation (k^2-5k+2) to the right and the answers are possible:

4, -4, 2, -2

I'm not sure if I see (4) used above when you substituuted-is that the one not generated??

**Reiny**, Monday, December 5, 2011 at 1:01pmof course!

You are right, I guess I can't read my own typing

4 is it!
