What is the HCF of two consecutive odd numbers?
Consecutive number are those number which follow each other in order. Thus, list consecutive of Odd natural number is 1, 3, 5, 7, 9, 11, 13, . . .
- For 1 and 3, only common factor is 1.
- For 3 and 5, only common factor is 1.
- For 5 and 7, only common factor is 1…
Similarly for each consecutive pair only possible common factor is 1.
So, HCF of two conscutive odd numbers is 1.
How Many Odd Numbers are Between 1 and 100?
As every other integer is odd and between 1 and 100 there are 98 number(not including 1 and 100). Thus, half of them must be even and half of them are odd number. Therefore there are 49 Odd numbers between 1 and 100.
What is Sum of First ‘n’ Odd Natural Numbers?
1 + 3 + 5 + 7 +… up to n terms
Consider this Arithmetic Progression, a = 1, d = 2 and using summation of n terms of A.P.
Required Sum = n/2{2a + (n – 1)d}
= n/2{2 + (n -1)2}
= n/2{2 + 2n – 2}
= n/2{2n} = n2
Thus, sum of first n odd natural numbers is n2.
Is Zero an Odd Number?
