Question

11. Any one of the numbers a, a + 2 and a + 4 is a multiple of:
(a)2
(b) 3
(c) 5 (d) 7​

Answer 1

Answer:

the number 1 + 2 and a + 4 is a multiple of 2

Answer 2

The required "option a) 2" is correct.

Step-by-step explanation:

We have,

a,  a + 2 and a + 4

To find, any one of the numbers a, a + 2 and a + 4 is a multiple = ?

∴ a,  a + 2 and a + 4

= a,  (a + 2)(a + 4)

Put a = 1, we get

= 1 (1 + 2)(1 + 4)

= 3 × 5

Put a = 2, we get

= (2 + 2)(2 + 4)

= 2 × 4 × 6

= 24

Thus, any one of the numbers a, a + 2 and a + 4 is a multiple of 2.

Thus, the required "option a) 2" is correct.
