Question

for some integer m,every even integer is of the form
(1)m+2
(2)2m
(3)2m-1
(4)2m+1

Answer 1

(2) 2m because product of any number by 2 is even.
Example :-
Let m be -4
2m = -4×2
= -8 which is even
Example 2:-
Let the resultant number be -46
2m = -46
m = -46/2
= -23

Option is (2)

2m

================

Put m = 1,2,3,4,5,-1,-2,......

→ 2(1) = 2

→ 2(2) = 4

→ 2(-3) = -6

→ 2(-10) = -20

The above results are all even numbers.

So,For some integer m,every even integer is of the form 2m.
