HE sequence {Fn} defined recursively by adding two
preceding terms with initial values F0 = 0, F1 = 1, is
called Fibonacci sequence. These sequences are generalized in
several directions in recent past, some by retaining the initial
conditions and imposing a change in the recurrence relation,
or others by retaining the recurrence relation and altering
the initial conditions. For instance, S.Falcon and A.Plaza
introduced the general k-Fibonacci sequence while studying
the recursive application of two geometrical transformation
used in the Four-Triangle Longest-Edge (4TLE) and many
properties of these numbers are deduced directly from
elementary matrix algebra (see [1]). Yashwanth K.Panwar
et al.(see [2]) introduced the notion of k-Fibonacci-Like
numbers (in short k-FLNs) aiming to generalize several
identities involving classic Fibonacci numbers to k-FLNs
with the aid of following Binet’s formula proved by them
Sk,n = 2{
r
n+1
1 − r
n+1
2
r1 − r2
} (1)
for n ≥ 0, where r1 and r2 are the roots of q
2 − kq − 1 = 0
with r1 > r2. Unfortunately, this formula (1) is incorrect as
it yield Sk,1 = 2k instead of its actual value Sk,1 = 2. The
purpose of this study is to introduce the notion of Generalized
