Question
The pattern formed by all odd numbers is correctly represented by the expression
Answer: Option A
:
A
Even numbers are divisible by 2.
So, all even numbers can be represented by 2 × n; where n represents whole numbers 0, 1, 2....
All, even number are succeeded by an odd number.
∴ 2n+1 gives the pattern formed by odd numbers.
For n=0, 2n+1 = 2 × 0 + 1 = 1
For n=1, 2n+1 = 2× 1 + 1 = 3
For n=2, 2n+1 = 2× 2 + 5 = 5.
So, it is clear that A is the correct option.
