if the nth term of a number sequence is n squared-3, find the first 3 terms and the 10th term

Sagot :

The first three terms of the number sequence are 1, 1/8, and 1/27. And the tenth term of this sequence is 1/1000.

We have been given the nth value of a number sequence that is,

           an = n^– 3

We can find the terms by replacing n with required values.

Thus the first term , a1 = (1)^– 3

                                         = 1

Second term, a2 = (2)^– 3

                             = 1/8

Third term, a3 = (3)^– 3

                          = 1/27

Tenth term, a10 = (10)^– 3

                             = 1/1000                            

Hence the first three terms of the number sequence are 1, 1/8, and 1/27. And the tenth term is 1/1000.
