Answer 1

$\huge \mathfrak\red{Answer}$

The number series 1, 2, 3, 4, . . . . , 29, 30. Therefore, 465 is the sum of positive integers upto 30.

Answer 2

the first 30 natural number =>

1,2,3.....28,29,30

applying the formula of finding the sum between natural numbers=>

Sum = n/2 x (a + Tn)

{ here a-first term, tn - total number}

=> 30/2× (1+30)

=> 15×31

=> 465

hence the sum of natural number between the first 30 natural number is 465
