Think of the sequence as 1 1 3, 2 4 6, 5 25 ?

Edited for typo. I should have changed my answer while I was at it. smiling smiley

Start with 1; square; add 2; subtract 1; repeat.

1, 1, 3, 2, 4, 6, 5, 25, 27, 26, 676, 678, 677, 458329, 458331, 458330, 210066388900, 210066388902, 210066388901, 44127887745906175987801, 44127887745906175987803, 44127887745906175987802

Beat me to it, I agree, it is a tough one.

Carm--choices on number 2 were 2, 15, 18, 32, 28?

A good friend took this test yesterday, and he knows l like these things so he forwarded some to me--and I was stumped on these 3. It may be due to the late hour--and at 50 years old--it has been awhile since I have done these.

Thanks again so much...Once I see your sequence--I kick myself--since it is now so clear :-)

Pretty sure that 6-2 =4.

2 6 3 8 6 12

Plus 4, minus 3, plus 5, minus 2, plus 6, minus 1? Just increase the number to be added by 1 every time, and decrease the number to be subtracted every time. And what to do after you get to 11...

That doesn't give a number from your '2, 15, 18, 32, 28' list of choices either. Hmm.

Yeah, I messed up when I was working the problem tongue sticking out smiley

Cant get the second one though.
2 6 3 8 6 12
2+4=6-3=3+5=8-2=6+6=12-1=11
+4, -3,+5, -2,+6, -1 <-is this last number right?

¿Possible answers: 2, 15, 18, 32, 28¿

EDIT: mikebw. Looking at the problem. Its adding positive one to both the negative and positive number. So after 11 it would be 18
2+4=6-3=3+5=8-2=6+6=12-1=11+7=18
+4,-3,+5,-2,+6,-1,+7,0,+8,+1

+4+1=5
-3+1=-2

ahh, but we still can't get 18 to follow 12 immediately. Perhaps Ken Sp. forgot to include the 11 in his sequence?

TheCaber, this is what I get.

"Search: 3, 9, 4, 5, 25, 20, 21, 441
I am sorry, but the terms do not match anything in the table. "

And that one was easy.
