Question

if sum of the first 10 natural numbers is S1 and that of the first 10 whole numbers is S2 . then s1-s2 is
​

Answer 1

Answer:

Natural no. 1,2,3,4,5,6,7,8,9,10

whole no.0,1,2,3,4,5,6,7,8,9

Step-by-step explanation:

if we add first 10 natural no. it comes 55

add first whole no. it comes 45

subtracting S1 by S2

55-45

=10

Answer 2

Answer :

10

Given :

• Sum of first 10 natural numbers = $S_1$
• Sum of first 10 whole numbers = $S_2$

To Find :

• $S_1 - S_2$

Solution :

Sum of first 10 natural numbers

→ 1 + 2 + 3 + ..... + 10

Sum of first 10 whole numbers

→ 0 + 1 + 2 + .... + 9

We know that,

★ Sum of first n natural numbers = n(n+1)/2

$S_1 - S_2$

= (1 + 2 + ... + 10) - (0 + 1 +.... + 9)

= [10(10+1)/2] - [0+(9(9+1))/2]

= 55 - 45

= 10
