Given the first term and the common difference of an arithmetic sequence find the recursive formula and the three terms in the sequence after the last one given.
20) 4, -39, d--
a,
22) a = -9.2, d = 0.9
21) 4 =-26, d = 200

answer: it's a

step-by-step explanation:

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right

60: 45 =12: 9 =4: 3 so the answer is 4: 3

zero

step-by-step explanation:

f(2)= x-2

plug in the 2 in the "x"

f(2)=2-2

f(2)=0
