Using a little algebra, and assuming that \"a\" is the nth Fibonacci Number and that \"b\" is the next Fibonacci number after \"a\" explain why 2 odd Fibonacci number precede every even one Solution beacuse fibonacii terms are sum of previous two consecutive fibonnaci terms so if anyone is even : : and other is odd : then there sum is ODD : so next terms comes out again ODD but nwxt terms comes out = EVEN.
