Question

Find the first 5 terms of the sequence
a1 = -7 an = an-1+6

Answer 1

\[a_1=-7\]\[a_n=a_{n-1}+6\]
a_2=-7+6=-1
a_3=-1+6=5
a_4=5+6=11
a_5=11+6=17

(By the way, this is called arithmetic sequence with first term -7 and common difference 6)

Answer 2

Thanks ! for this one:

a1 = 6 an+1=-2an+3

is the second term 3/2?

Answer 3

\[a_1=6\]
\[a_{n+1}=-2a_n+3\]
\[n=1 -> a_2=-2a_1+3\]
\[a_2=-12+3=-9\]
