Find the first three terms of the sequence defined below, where n represents the position of a term in the sequence. start with n = 1. -2n − 10

The first three if the sequence defined are -11, - 13 and - 15.

Step-by-step explanation:

Here, the nth term of the sequence is given as n = - 2n - 10

So, For n = 1 : the first term =  - 2(1) - 10

                                            =  -2 - 10 = -12

For n = 2 : the second term =  - 2(2) - 10

                                            = -4 - 10 = -14

For n = 3 : the third term =  - 2(3) - 10

                                            =  -6 - 10 = -16

Hence, the first three if the sequence defined are -12, - 14 and - 16.

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.
