If Sn=2+0.4n find initial velocity and acceleration

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

If S_n =2+0.4n find initial velocity and acceleration

If S_n =2+0.4n find initial velocity and acceleration

If S_n = 5n^2 + 3n , then find its n^(th) term.

16.The Sum Sn of first 'n' even natural numbers is given by the relation Sn=n(n+1) . Find n,if the sum is 420.

If S_n = n² + 2n , then find first term & common difference?
