Question

Use mathematical induction to prove the statement is true for all positive integers n, or show why it is false. 12 + 42 + 72 + ... + (3n - 2)2 =

Answer 1

=?

Answer 2

this makes no sense...(3n-2)^2 would be

1+16...

Answer 3

this is what it actually looks like sorry
1^2 + 4^2 + 7^2 + ... + (3n - 2)^2 =

Answer 4

correct

Answer 5

=?

Answer 6

that is the whole problem...

Answer 7

it makes no sense.

Answer 8

there is nothing to prove

Answer 9

what statement is true?

Answer 10

look again...

Answer 11

how do I prove the problem is true??

Answer 12

THERE IS NOTHING TO PROVE

you wrote this

prove that something =

but you didnt tell us what we need to prove its equal to

Answer 13

thats like me saying

Prove that every animal has

Answer 14

has what?!

Answer 15

there MUST be something after the = sign

Answer 16

Use mathematical induction to prove the statement is true for all positive integers n, or show why it is false.

Answer 17

@jbrimson ?

Answer 18

dude look at any other problem that tells you to prove something by induction. do they have something after the equal sign?

Answer 19

\(1^2+4^2+......+(3n-2)^2=\frac{1}{2}n(6n^2-3n-1)\)

I can show you how to prove this...

Answer 20

and since I can prove this, there is nothing else that you could put after the equals sign to make it true. Would you like me to do so?

Answer 21

12 + 42 + 72 + ... + (3n - 2)2 = n(6n^2-3n-1)/2
sorry I see what I left out

Answer 22

lol

Answer 23

really dude/?

Answer 24
