Answer:
The answer is (-2)
Step-by-step explanation:
<h3><u>Given</u>;</h3>
- a₁ = (-6)
- a₂ = (-4)
- and so on,
<h3><u>To</u><u> </u><u>Find</u>;</h3>
Here, we will use AP
Now, Common Difference (d)
d = a₂ – a₁ = (-4) – (-6) = (-4) + 6 = 2
Here, Common Difference (d) is 2
So,
a₃ = a₂ + d
a₃ = (-4) + 2
a₃ = -2
Thus, The missing number in this sequence is (-2).

Answer:
y = -29/19 and x = -44/19
Step-by-step explanation:
3x + 2y = -10 multiply by -2 ⇔ -6x - 4y = 20
2x - 5y = 3 multiply by 3 ⇔ <u> 6x - 15y = 9 </u>
Add the two equation -19y = 29
y = -29/19
Use equation one and solve for x
3x + 2(-29/19) = -10
3x - 58/19 = -10
3x = -10 + 58/19
3x = -190/19 + 58/19
3x = (-190 + 58)/19
3x = -132/19
x = - 132/ 19 ÷3
x = -44/19
8 would be the constant but in this situation there is a variable next to it so I’m not sure if it would be considered a constant
