Determine t3,t7, and tn for the arithmetic sequences with properties below
A) a=2x and d=5x
B) t14=46 and t19=100
Also, how would i create a spreadsheet file and graph for the sequence in B)
Thank you
The general term of an arithmatic progressions is:
$\displaystyle t_n=a+d \times n$
(assuming the zeroth term is $\displaystyle a$).
So:
$\displaystyle t_3=a+d \times 3$
and
$\displaystyle t_3=a+d \times 7$
Now just replace $\displaystyle a$ and $\displaystyle d$ with the given expressions and simplify.
