There are no two consecutive whole numbers that sum to 142.With two consecutive whole numbers, one is even and the other odd, and their sum will be odd, but 142 is even.Two consecutive even numbers that sum to 142 are 70 and 72.
I think you are talking about three numbers 743, 142, and 986425. If the least significant digit in a number is odd, the number is odd. If the least significant digit in a number is even, the number is even. You can also divide the number by 2 and if two goes into the number evenly without a remainder then the number is even. If there is a remainder, the number is odd.
Odd. Even + Even = Even Odd + Odd = Even Odd + Even = Even + Odd = Odd
odd * odd = odd answer even * even = even answer odd * even = even answer
even times even = even odd times even = even odd times odd = odd
Yes. Even + Even = Even, Odd + Odd = Even and Even + Odd or Odd + Even = Odd
(142 x 2) - 1 = 283
No. Sum of odd + odd = even Sum of odd + even = odd Sum of even + even = even
Always. even + even = even odd + odd = even even + odd = odd odd + even = odd To summarise, if you add like numbers you get even, otherwise you get odd.
even times even = even odd times even = even odd times odd = odd
it is even
even times even = even odd times odd = odd even times odd = even
