Question

can anyone find out the 8th and the nth term of the sequence

"3,6,7,-2"

and the nth term of the sequence

"7,5,3,1..." ??

Answer 1

for the second one

t(n) = 7 - 2(n-1)

Answer 2

thanks :) and do you have any idea about the other one? it seems to be very vaque :P

Answer 3

the first one i cant figure out

Answer 4

3
3+ 3 = 6
6+ 1 = 7
7+(-9) = -2

1(3) + (a) = 6
2(3) + (a) = 7
3(3) + (a) = -2

3x + (a) = y

0,3
1,6
2,7
3,-2

im wondering if we match a curve to these points if that would generate a function ....

Answer 5

well, actually: "3,6,7,-2" only has 4 terms to it; without the ... there is no other terms to find

Answer 6

hahahahaha

Answer 7

:) unless it was a typo, thats the best answer I can come up with ;)

Answer 8

actually, it had to do with two other sequences. there was

4,9,16,25
and
1,3,9,27. so this sequence is the first one minus the second one. 4-3, 9-3, 16-9, 25-27, etc.
