Read Solution (Total 2)
-
- 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 - 9 years agoHelpfull: Yes(14) No(0)
