Question
Prove each of the statements in 10-18 by mathematical induction
12.
1/(1*2)+1/(2*3)+. . . + 1/(n(n+1))=n/(n+1), for every integer n> =1
P(1)
1/(1(1+1) = 1/2
P(1) is not true
P(2)
1/(2(2+1)) =1/6 +1/2 =2/3 =2/(2+1)
P(2) is true
P(k) = 1/(1*2)+1/(2*3)+. . . + 1/(k(k+1))=k/(k+1)
P(k+1) = 1/(1*2)+1/(2*3)+. . . + 1/(k+1(k+2))=k+1/(k+2)
