-12,-28,-44, ...

Step-by-step explanation:

hello:

a (n) - a (n-1) = - 16 (common differnce for arithmetic sequence)

-44 - (-28) = (-28) - (-12) = - 16

the ni-eme term is : a (n) = a (1) + (n-1) d d = - 16 and a (1) = - 12

so : a (n) = - 12 + (n-1) (-16)

a (n) = - 16n+4

continue for 61st term n = ?

when : n=? a (?) = - 16 (?) + 3 = ...
