Answer:

<u>AP equation:</u>

<u>The equation is:</u>

  • t_n=3+(n-1)*6=3+6n-6=6n-3

<u>Next two terms are:</u>

  • t_3=6*3-3=15\\t_4=6*4-3=21

I already made an attempt at this question and I would just like to check my answer z = ?
Salsk061 [2.6K]

So we have the equation:

\frac{z+9}{4}=2.1

Then we need to multiply by 4 on both sides to get rid of the denominator on the left:

z+9=8.4

Then we subtract 9 on both sides to solve for z:

z=-0.6

Therefore the answer is z = -0.6.
