Answer:

56/19

Step-by-step explanation:

∵ z = 8

∴ 4(8) + 8 - 6 =34

∵ x = 3

∴ 7z /(4 + 5x) = 7(8) ÷ (4 + 5 × 3) = 56 ÷ 19 = 56/19

∵ y = 12

∴ y² ÷ 3z = (12)² ÷ 3(8) = 144 ÷ 24 = 6

Answer:

176

Step-by-step explanation:

First term (a) = 29

Common difference (d) = 32 - 29 = 3

For calculating the 50th term , n = 50

Now

$t_{50} = a + ( n - 1) d\\t_{50} = 29 + ( 50 - 1 ) *3\\ t_{50} = 29 + 147\\t_{50} = 176$
