Question

What is the formula of displacement of the uniformly accelerated body during nth second.Its initial velocity is v and acceleration is a.
(1) S = v + (2n - 1)
(2) S =(a/2) (2n - 1)
(3) S = vn + a(2n - 1)
(4) S = v + (a/2)(21 - 1)

please answer!!!!!
ASAP​

Answer 1

The answer will be:

s = v + (a/2)(2n -1)
