If I used the terms 2, 3, 4, 8 consecutive terms of the Fibonacci sequence. "a" is the first and fourth terms and "b" is twice the product of the second and third terms. "c" will be the sum of the squares of the second and third terms.

I think I need to set the problem with the equation a^2 + b^2 = c^2

6^2 + 14^2 =

36+196=232

I do not think that I am doing this correctly and could use some help.

**Reiny**, Monday, October 3, 2011 at 2:18pmI love the Fibonacci sequence, but I can't make any sense out of your question

First of all the consecutive terms of the sequence would be

2, 3, 5, 8, 13, ....

According to you , "a" is 2 "and" 8 . Are we adding them? , ok, so a = 10

b = 2(3)(5) = 30

c = 9 + 25 = 34

is 10^2 + 30^2 = 34^2

no, it is not

How did you get the numbers 6 and 14????

**Jennifer**, Monday, October 3, 2011 at 3:49pmI think it is the fibonacci numbers and the wording of the word problem. I thought I had to add 4 and 2 together to get the 6 and then square it. I am just confused. Thanks

**Reiny**, Monday, October 3, 2011 at 4:37pmYou did not read my reply carefully.

We form a new Fibonacci number by adding the two previous numbers, so 4 does not fit the pattern,

The 4 should have been a 5.

Please type the question exactly the way it appeared.

**Jennifer**, Monday, October 3, 2011 at 5:49pmThank you Jennifer! I just figured out where I went wrong in wording the problem.

a= 2x8=16

b=2x15=30

c=9+25=34

16^2+30^2=34^2

256+900=1156

1156=1156

Thank you for helping to guide me in the right direction.

One more problem to go by Friday...I just may be calling on you!
