Question

A sequence has a second term of 1 and a common difference of -3.

The fifth term of the sequence is _____.

Answer 1

\[a_2 - a_1 = d\]
so
\[1 - a_1 = -3\]
get a_1
then use
\[a_n = a_1 + (n - 1)d\]
to find the fifth term

Answer 2

so would the 5th term be -5?

Answer 3

nah nah.....
u need to plug n = 5 in the equation
so it would be
\[a_5 = a_1 + (5 - 1)d\]
plug a_1 = 4
and d = -3

Answer 4

ooh i see
