Write the first three terms of the following sequences whose nth terms are given by `a_n=[n(n-2)]/3`

Text Solution

Verified by Experts

Here, `a_n = (n(n-2))/3`
So,
`a_1 = (1(1-2))/3 = -1/3`
`a_2 = (2(2-2))/3 = 0`
`a_3 = (3(3-2))/3 = 1`
So, first three terms of the given sequence will be `-1/3,0,1.`
