Question 63

Choose a letter x, y, z, p etc...., wherever necessary, for the unknown (variable) and write the corresponding expressions for the given statement:

Two consecutive even integers.

Answer 1

$\begin{array}{cc}n& 2n\\ 0& 0\\ 1& 2\\ 2& 4\\ 3& 6\\ & \end{array}$

Analysing the table above, we can understand that any even integer can be written as 2n, where n is an integer.

Let the first integer be 2n.

Consecutive integer = 2n + 2

$\therefore$Two consecutive even integers can be expressed as 2n and 2n + 2.
