What are the first four terms of the sequence given by the formula below a_n = -2n + 4

Solution:

Given, a_n = -2n + 4

We have to find the first four terms of the sequence.

a(1) = -2(1) + 4 

= -2 + 4 

= 2

a(2) = -2(2) + 4 

= -4 + 4 

= 0

a(3) = -2(3) + 4 

= -6 + 4 

= -2

a(4) = -2(4) + 4 

= -8 + 4 

= -4

Therefore, the first four terms of the sequence are 2, 0, -2 and -4.
