Hello Mortals

Odd numbers between 0 to 50 are
1, 3,5,7.....,49.

a = 1
d = 2
l = 49

A/q,

a + ( n - 1) d = tn
=> 1 + ( n - 1) 2 = 49
=> ( n - 1) 2 = 48
=> ( n - 1) = 24
=> n = 25.

So,
Sum = n/2 × ( a +l)
= 25 /2× ( 1 +49)
= 25 /2 × 50
= 25 ×25
= 625

ASHTRIXofficial: It's about what Cosmology contains ( as a subject matter)

ogr: oh i think it relates with your profile picture

ASHTRIXofficial: When you study Cosmology then you should have to know about 4-dimenaional Continuum and the relative space ( i. e Minkowski)

ogr: i know about only three dimensions what about 4th dimension

ASHTRIXofficial: there are 11 dimensions a according to Einstien and Hawking. 4th dimension is time. And some research told that it may be possible that there are 26 dimensions.

ogr: its amazing

ogr: i like to study about space and time but i dont have enough time to study

ogr: because my syllabus is enough to study

ogr: hey tell me something about cosmology

ASHTRIXofficial: no one has time, they manage it. or go to singularity, time will certainly stop for you

Solution :

The odd numbers between 0 and 50 are 1, 3, 5, .. , 49. They form an AP and there are 25 terms.

∴ Their sum = $\frac{25}{2} (1 + 49) = \frac{25}{2} \times 50$

= 25 × 25 = 625
