​

Answer 1

Heya....

Answer:

Given: 2,4,8,16......

Common Difference:T2-T1

=4-2

=2

Again,

=T3-T2=8-4=4

Hence it is not an A.P

Answer 2

Step-by-step explanation:

2,4,8,16

d=a2-a1 ---------1)

d=a3-a2---------2)

from equ 1)&2)

a2-a1=a3-a2

4-2=8-4

2=4

difference can't be different therefore this doesn't form A.P.
