A car traveling at 10 m/s starts to slow down. It comes to a complete stop in 20 seconds. What is its acceleration?

correct option 1

a=v/t

a=10/20

a=1/2

or

a=0.5m/second square

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18
