Question

12th term of G.P. 2, 4, 6, 8,
will be .....​

Answer 1

Given:

• A Arithmetic series 2,4,6,8... (correct)

To Find:

• The 12 th term of the series.

Answer:

• The series is 2,4,6,8,...........

Now , here common difference is (4-2)=2.

And first term is 2

So , nth term of an AP is given by ,

=> T n = a+(n-1)d

=> T 12 = 2+(12-1)2

=> T 12 = 2+11×2

=> T 12 = 2+22

=> T 12 = 24.

Answer 2

Answer:

a12 = 2 + (12-1)2

a12 = 2 + 22 = 24
