3)

▏=> Primeiro termo, n = 1:

▏=> Segundo termo, n = 2

▏=> Terceiro termo, n = 3

▏=> Quarto termo, n = 4:

▏=> Quinto termo, n = 5

Sequência:

(2, 4, 6, 8, 10)

4)

✅ a)

$4\left(2x-5\right)=3-\left(-2x+1\right)\\8x-20=2x+2\\8x-20+20=2x+2+208x-2x=2x+22-2x\\6x=22\\x = \frac{22}{6}\\x=\frac{11}{3}$

✅ b)

$50+\left(3x-4\right)=2\left(3x-4\right)+26\\3x+50-4=2\left(3x-4\right)+26\\3x+46=6x+18\\3x=6x-28\\-3x=-28\\\frac{-3x}{-3}=\frac{-28}{-3}\\x=\frac{28}{3}$

✅ c)

$\frac{x}{4}-1=2+\frac{x}{10}\\5x-20=40+2x\\5x=2x+60\\3x=60\\\frac{3x}{3}=\frac{60}{3}\\x=20$

✅ d)

$\frac{4}{5}+\frac{x}{2}=\frac{x}{3}-1\\24+15x=10x-30\\15x=10x-54\\15x-10x=10x-54-10x\\5x=-54\\\frac{5x}{5}=\frac{-54}{5}\\x=-\frac{54}{5}$
