Question 62

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 odd integers.

Answer 1

$\begin{array}{ccc}n& 2n& 2n+1\\ 0& 0& 1\\ 1& 2& 3\\ 2& 4& 5\\ 3& 6& 7\\ & & \end{array}$

Analysing the table above, we can understand that any odd integer can be written as 2n + 1, where n is an integer.

Next odd integer can be written as (2n + 1) + 2 = (2n + 3).

$\therefore$Two consecutive odd integers can be written as (2n + 1) and (2n + 3).
