1. Let smallest number be x. So next one is x+2, then x+4 and largest is x+6


x+6 = 2(x) - 14
x+6 = 2x - 14
6 = x - 14
20 = x


so numbers are 20, 22, 24, 26


2. Let smallest angle = a
next angle is a+1
largest is a+2


All 3 add to 180 degrees, so (a+a+1+a+2) = 180
3a+3 = 180
3a = 177
a = 177/3
a = 59


so 3 angles are 59, 60 and 61 degrees


3. Let 2 numbers be x and y, with x being the larger.


x+y = 18
3x - 4y = 5


You solve this simultaneous equation.
