<h2>✏️ Development:</h2>

✍ Having as t₃ =10 and t₁₀ = -4.  We have to find the common ratio.

❑  If, in front of the sequence from 3 to 10, there are 7 numbers, that is, 7 terms, we have to find a pattern, what I used was this one.

\large {\text {$ \sf   7 \longrightarrow Number \: Terms $}}

\large {\text {$ \sf x \longrightarrow rasion $}}

          We see that in the calculation, the only number that fits is -2.

➤ Because if we stop to think about it, we have -2 of common ratio among these 7 terms is -14, so 10-14 = -4

So the hypothesis is correct!

➜ Being right as -2 and resuming the terms of 10, we have:

\huge {\boxed {\blue {\sf t_{10}, t_{11},  {\bf t_{12}} =  \{ -4 , -6 , \bf -8 \} } }}

So t₁₂ is equal to -8.

Solve each equation for y. Then find the value of y for each value of x. y+3x=8;x=-2,0,2
damaskus [11]
Y=-3x+8
when x=-2:
y=-3(-2)+8
y=6+8
y=14
when x=0
y=-3(0)+8
y=0+8
y=8
when x=2
y=-3(2)+8
y=-6+8
y=2
