Question

How do you write the first six terms of the sequence `a_n=3-n`?

Answer 1

2, 1, 0, -1, -2, -3

Explanation:

Since this is an arithmetic sequence which is defined on natural numbers the first six terms can simply be obtained by substituting n with 1, 2, 3, 4, 5, 6.

`i.e.`

`a_1 = 3-1 = 2`
`a_2 = 3-2 =1`
`a_3=3-3=0`
`a_4=3-4=-1`
`a_5=3-5=-2`
`a_6=3-6=-3`
