Question

if an =2n , its second term is
a.4
b.0
c.2​

Answer 1

Answer:

a.4

Step-by-step explanation:

an=2n

=2(2)

=4

first term is 2(1)=2

so second is 4

and third is 2(3)=6

it goes on this way

Answer 2

Answer:

A. 4

Step-by-step explanation:

Given that, an=2n

If we take n=1 i.e., a1

an= 2(1)

an=2 [ thus first term is 2 ]

Similarly if we take n =2 i.e., a2

an= 2(2)

an= 4 [ thus second term is 4 ]
