Question

If an = 2n – 1 then value of an+1 is
​

Answer 1

Answer:

2n

Step-by-step explanation:

an = 2n – 1

an + 1 = 2n

Answer 2

Given, an = 2n - 1 .

Then, the value of an + 1 is given below,

an = 2n - 1 __________ eq.(i)

By putting the eq.(i) in an + 1, we get

an + 1 = (2n - 1) + 1

By removing the parenthesis or the bracket, we get

an + 1 = 2n - 1 + 1

= 2n

(As the opposite number got cancelled)

Therefore, the value of an + 1 is 2n .
