If A=4n+2;nisanaturalnumber and B=3n;nisanaturalnumber then A∩B is equal to ?
12n2+6n|nisanaturalnumber
24n–12|nisanaturalnumber
60n+30|nisanaturalnumber
12n–6|nisanaturalnumber
Explanation for the correct option:
Given A=4n+2|nisanaturalnumber=6,10,14,18,…
B=3n|nisanaturalnumber=3,6,9,12,….
(A∩B)=6,18,30,…
=6+(n-1)12,n∈N=12n–6,n∈N
Hence, option (D) is the correct answer.
