A(1)=20

Paladinen [302]

Answer:

-14

Step-by-step explanation:

You've got a(1)=20

a(1) means a(n) when n=1

the sequence is telling you to take the previous value of a(n), which is a(n-1) and subtract 17

then:

a(2) = a(1)-17 = 20 - 17 = 3

a(3) = a(2) - 17 = 3-17 = -14

Solve the equation. 9+2 14x – 31 = 19<br> Please answer it step by step

siniylev [52]

Answer:

$x = \frac{41}{28} = 1 \frac{13}{28}$

Step-by-step explanation:

$9 + 2(14x - 3) = 19$

$9 + 28x - 31 = 19$

$- 22 + 28x = 19$

$28x = 19 + 22$

$28x = 41$

$\boxed{\green{x = \frac{41}{28} = 1 \frac{13}{28}}}$
