Question

what does for example 6n mean?

Answer 1

6n means that n is a variable that is being mulitpled by 6

Answer 2

for example 6(9) is going to be 6 x 9 which is 54

Answer 3

what would I put when the question is "for any whole number,n,the value of 6n-1 is always a prime number explain how this is wrong?

Answer 4

so what sign whole number ,,n" -- i think every natural numbers
so than if you add value for n in case of 6n-1 you need getting always a prime number

so for n=1 result 6*1 -1=5
for n=2 --- 6*2 -1=11
for n=3 --- 6*3 -1=17
for n=4 --- 6*4 -1=23
for n=5 --- 6*5 -1=29
for n=6 --- 6*6 -1 =35 so what not is a prime number si than result that this statement is wrong
