Question

Find the first five terms;
a1=-5, an = 4a n-1 +10

Answer 1

do you see the relationship?
write out the first 3 terms

a1 = -5
a2 = a1 + 10 = -5 + 10 = 5
a3 = a2 + 10 = 5 + 10 = 15

Answer 2

@bibby isnt the eqn: a_n = 4a_n-1 +10 ?

Answer 3

I can't read. whoops.
a1 = -5
a2 = 4(a1)+10 = 4(-5) + 10 = -20 + 10 = -10

Try the rest

Answer 4

yup :)
so a3=4(a2)+10=4(-10)+10=-30
