A sequence {An} is defined A(1)=0&A(n+1)=A(n)+2(n)WHAT IS VALUE OF A(100)
[*TCS-2012*]
(A)9902 (B)9900 (C)10100 (D)9904

• a(1)=0 ----------------------------1.
  a(n+1)=a(n)+2(n)-----------2.
  put n=1 in 2.
  we get a(2)=2
  den put n=2 in 2.
  we get a(3)=6
  similarly put n=3
  we get a(4)=12
  u can see for n+1=1+1=2 2×1=2
  n+1=2+1=3 3×2=6
  n+1=3+1=4 4×3=12
  similarly n+1=99+1=100 100×99=9900
