Question 1165510
<pre>
Instead of doing yours for you, I'll find the 47th term of the sequence
560, 505, 450, 

First subtract the 2nd term minus the 1st term, 505-560 = -55
Now subtract the 3rd term minus the 2nd term,   450-505 = -55

So this is an arithmetic sequence since they are the same, and the
first term a<sub>1</sub> = 560, and the common difference = d = -55 

The formula is:

{{{a[n]=a[1]+(n-1)d}}}

Substituting:

{{{a[47]=560+(47-1)(-55)}}}

{{{a[47]=560+(46)(-55)}}}

{{{a[47]=-1970}}}

Answer: -1970

Now do yours the exact same way.
