8, 13, 18, 23, 28, etc.
4y + 10 = -18 4y = -28 y = -7
Halfway between 18 and 28 is (18 + 28) ÷ 2 = 23.
18
16 + 16 + 16 + 17 + 18 + 18 + 18 + 19 + 19 + 20 + 20 + 20 + 21 = 238
18 + 10 + 28 + 10 = 66
18 + 10 = 28
58
The sum is 93.
13 + 16 + 18 + 20 + 21 + 26 + 27 + 27 + 28 + 36 + 39 + 42 + 43 = 356
6z + 28 = 12z + 10 18 = 6z 3 = z
24-18=6 35-7=28 28+6=34 so 34 is the answer
13
1+1.8=2.8
