Find the sum of odd integers from 1 through 57

Step-by-step explanation:

First we find n:

Tn = a+ (n-1)d

Here,

a=1 ,Tn =57

d=2 ( difference between numbers is 2)

Now,

57 = 1 + (n-1)2

57 = 2n -1

58/2 = n

Or n = 29

Now, We find sum :

Sn = n/2 { a+Tn}

= 29/2 { 1 + 57 }

= 29/2 ( 58)

= 29 x 29

= 841

x = 25

step-by-step explanation:

a^2+b^2=c^2

7^2+24^2=c^2

49+576=625

sqrt625=25

x=25

.there can be infinite values of m and n that can satisfy the above equation. for each value of m of m or n. there maybe infinite sets of solution for the above
