Question 1.

Is the phenomenon of all the expressions having the same parity limited to taking 4 numbers? What do you think? Class 8

Solution:

Yes. But in case of five consecutive numbers, the parity will be odd, instead of even, for six consecutive numbers, parity will be even, for seven consecutive numbers, it will again be odd, and so on.

Question 2.

Write a few algebraic expressions which always give an even number. Class 8

Solution:

4a + 6x; 8x + 2y; 10x — 4y; 7x × 4z, etc.
