Answer:
The 105th term of given sequence is 
.
Step-by-step explanation:
The given sequence is
It can be rewritten as
Here the first term is 0.5.
It is an arithmetic sequence because it has common difference.
The nth term of an AP is
where, 
is first term and d is common difference.
Substitute 
and 
in the above formula.
We need to find the 105th term of given sequence.
Substitute n=105 in the above equation.
Therefore the 105th term of given sequence is .
Answer:
5=b
Step-by-step explanation:
Eliminate the parenthiesies --> n-2+7 = bn
Move the variables to one side (they cancel eachother out) --> -2+7 = bn
Solve --> 5=b
Answer:
=14x3−166x2−208x
Step-by-step explanation:
(7x+8)(x)(2x−26)
=((7x+8)(x))(2x+−26)
=((7x+8)(x))(2x)+((7x+8)(x))(−26)
=14x3+16x2−182x2−208x
=14x3−166x2−208x
X/7 = 0.4 => x = 7 x 0.4 = 2.8
7/y = 0.4 => y = 7 : 0.4 = 17.5
