5. ### given that 1^2+2^2+3^2+.....+ k ^2= k *( k +1)*(2k+1)/6,what is the smallest integer k such that?

k ( k +1)(2k+1)/6 must be divisible by 100 means k ( k +1)(2k+1) divisible by 600 which is 5x5x2x2x2x3 2k+1 is odd, and only one of k or k +1 can be even so you need k or k +1 divisible by 8 one of k , k +1, and 2k+1 will always be divisible...

6. ### Show that the following equation has real roots for all values of k ?

( k -1)x^2+2x-( k -3)=0 suppose k -1=a and k -3=b so,a-b= k -1- k +3=2 so the equation becomes ax^2+(a-b)x-b=0 => ax^2+ax-bx-b=0 =>ax(x+1)-b(x+1)=0 =>(ax-b)(x-1)=0 x=-1 or x=b/a=( k -3)/( k -1)

9. ### Show that p_ k = p_( k -1) + (3k-2) for k >=2. Conclude that p_n = sum from k =1 to n of (3k-2).?

Let k ≥ 2. Then p_( k - 1) + 3k - 2 = ( k - 1)[3( k - 1) - 1]/2 + (6k - 4)/2 = [( k - 1)(3k - 3 - 1) + 6k - 4]/2 = [( k - 1)(3k - 4) + 6k - 4]/2 = (3k² - 7k...
