If a and b are whole numbers then verify a+b=b+a taking a=12and b=13.
Step I - Taking L.H.S.
a+b=12+13
= 25
Step II - Now taking R.H.S,
b+a=13+12
As, in both the addition the answer is same .
therefore, It is verified that a+b=b+a.
Fibonacci numbers Take 10 numbers as shown below:
a, b, (a + b), (a + 2b), (2a +3b), (3a + 5b), (5a +8b), (8a +13b), (13a + 21b), and (21a +34b).
Sum of all these numbers =11(5a + 8b) =11 × 7th number.
Taking a = 8, b= 13; write 10 Fibonacci numbers and verify that sum of all these numbers =11 × 7th number.
If a=-13,b=5andc=-11 Verify that a+b=b+a
if a and b are any two whole numbers and b < a, then a -b is a _______ number
