Question

write the first three terms in each of the sequence defined by the following:(i)an=3n+2...plz help fast..

Answer 1

hi,
we have,
an=3n+2
putting n=1,2 and 3,we get
a¹=3×1+2=3+2=5,
a²=3×2+2=6+2=8,
a³=3×3+2=9+2=11
thus the required first three terms of the sequence defined by an=3n+2 are 5,8and11.
thanks... hope it helps u..

Answer 2

hii priyam
you can solve this prob with pri's meathod but you can solve this prob also with my meathod ok
let's start
we have prob,
an=3n+2
put n =1,2and3 then we get,
a1=(3×1)+2=(3+2)=5,
a2=(3×2)+2=(6+2)=8
a3=(3×3)+2=(9+2)=11
now, solve the prob in the brackets then u will find solution automatic
THANKS
