Question

14. Find the sum of the odd numbers Between 0 and 50

​

Answer 1

Answer:

625

Step-by-step explanation:

in the series, we know first term 'a' = 1 and last term 'l' = 49

we know that $S_n = \frac{n}{2}(a+l)$.

there are totally 25 of=odd numbers between 0 and 50.

so let n = 25

now, $S_n = \frac{25}{2} (1+49)$

$S_n = 25(50)/2 = 25^2 = 625$

so sum of odd numbers between 0 and 50 is 625

Answer 2

Answer:

625

Step-by-step explanation:

in the series, we know first term 'a' = 1 and last term 'I' = 49

we know that Sn

(a+1).

there are totally 25 of=odd numbers between 0 and 50.

so let n = 25 =

now, Sn

25

(1+ 49) 2

Sn = 25(50)/2 = 252 = 625

so sum of odd numbers between 0 and 50 is 625
