Could I please have some help? Thanks

D

Step-by-step explanation:

There is a common difference d between consecutive terms, that is

d = - 1 -(- ) = - 1

d = -  2 - (- 1 ) = - 1

d = - 3 - (- 2 ) = - 1

This indicates the sequence is arithmetic with explicit formula

= a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = - and d = - 1 , thus

= - - 1 (n - 1) = - - n + 1 = - n , where n = 1, 2, 3, 4, ......

its d but looking at that hurts my eyes frfr
