Answer:
common difference(d) = 11
first term (a)=11
then the nth term
=a+(n-1)d
=11+ (n-1)*11
=11+11n-11
=11n
It is not likely because it is less then 50% which 50 is half and 25% is 1/4 chance.
The correct will be C because in order to get 18 you have to multiple 3 with 6. Since you multiplied them you have to multiple the rest with 6.
1/2x•6= 3x
1/3y•6= 2y
