Question

If the nth term of an A.P. is 6n – 4, then its common difference is:​

Answer 1

Answer:

common difference is 6

Step-by-step explanation:

The nth term is given by 6n-4

i.e.,

1st term :6×1-4=6-4=2

2nd term:6×2-4=12-4=8

and so on ..where you put n=3,4,5.....in 6n-4.

common difference:

a2-a1=8-2=6

Answer 2

Step-by-step explanation:

AP : 6n-4

a1 = 6n-4 = 6×1-4 = 6-4 = 2

a2= 6n-4 = 6×2-4 = 12-4 = 8

a3 = 6n-4 = 6×3-4 = 18-4= 14

d= a2-a1= 8-2 = 6

= a3-a2= 14-8 = 6

So it's common difference is 6
