This is an arithmetic sequence because each term is 7 greater than the previous term, so 7 is what is called the common difference...
Any arithmetic sequence can be expressed as:
a(n)=a+d(n-1), a=first term, d=common difference, n=term number.
We know a=1 and d=7 so:
a(n)=1+7(n-1)
a(n)=1+7n-7
a(n)=7n-6
The above is the "rule" for the nth term.
Hi there
To find The interest rate the formula is
R=I÷pt
r interest rate?
I interest earned 622.5
P principle 12450
T time 1 year
So
R=622.5÷(12,450×1)
R=0.05×100=5%
Hope it helps
