Find the first six terms of the sequence described by the following recursive formula: an = an – 1 + an – 2 where a3 = -5 and a4 = 3

Now we have:  -13, 8, -5, 3, -2, 1

Step-by-step explanation:

This is a Fibonacci sequence.

though modified.

so  a_n = a_(n-1) + a_(n-2)

with a_3 = -5,

a_4 = 3

a_3 = -5 = a_2 + a_1

a_4 = 3 = a_3 + a_2 = -5 + a_2

then   a_2 = 3 + 5 = 8

then.

a_3 = -5 = a_2 + a_1 = 8 + a_1

a_1 = -5 - 8 = -13

We now have:   -13, 8, -5, 3,

Now we can find  a_5  and a_6

a_5 = a_4 + a_3 = 3 + -5 = -2

a_6  = a_5 + a_4 = -2 + 3 = 1

Now we have:  -13, 8, -5, 3, -2, 1

step-by-step explanation:

it's 15

d

step-by-step explanation:

given

y + 3 = - 4(x - 2) ← distribute the parenthesis

y + 3 = - 4x + 8 ( subtract 3 from both sides )

y = - 4x + 5 → d
