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 =.....
70% increase
66
Use the combination formula.
-3
to eliminate 6x we need the same no. 6x but that should be negative. so
2X × -3 = -6X
and
6X+(-6X)=0

hope this is useful
