If `S_(n)=2+0.4n` find initial velocity and acceleration

A

2.2 units, 0.4 units

B

2.1 units, 0.3 units

C

1.2 units,0.4 units

D

2.2 units, 0.3 units

Text Solution

Verified by Experts

The correct Answer is:
A
`s_(n) = u + an - (1)/(2)a = (u - (1)/(2)a) +an ………. (1)`
`s_(n) = 2 + 0.4n ………… (2)`
from (1) and (2) 0.4 n =an , `u -(1)/(2)a = 2`
