Solve for the x in the equation <br><img src="https://tex.z-dn.net/?f=x%20%2B%203x%20%2B%205x%20%2B%207x%20%2B%20...49x%20%3D%20

Flauer [41]

Answer:

x=1

Step-by-step explanation:

x+3x+5x+7x+...+49x=625

(1+3+5+7+...+49)x=625 (1)

now consider s= 1+3+5+7+...+49

a=1

d=3-1=2

l=49

l=a+(n-1)d

49=1+(n-1)2

49-1=(n-1)2

48/2=n-1

n-1=24

n=24+1=25

s=n/2*(a+l)

s=25/2(1+49)

x=25/2×50

s=25×25=625

from (1)

625 x=625

x=625/625=1
