Question

Find the 61st term of the arithmetic sequence

Answer 1

Answer:

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 =.....
