Question

Find the thirtieth term of the following sequence.

-6, -4, -2, 0, ...

Answer 1

if you want to do it the easy way... you're adding 2 every term

to what is -6 + 12*(2)?

Answer 2

you multiply by 12 because you start with the first term, and you need to find the value 12 terms later for the 13th term

Answer 3

The formula needed for this arithmetic progression is
\[n ^{th}\ term=a+(n-1)d\]
So the thirtieth term is
\[-6+(30-1)2=(2 \times 29)-6\]
