Answer:
The answer is -5.
Step-by-step explanation:
As you look at the first 3 terms, all have the common difference of 4. So the next term after -1 is :
19 - 4 = 15
15 - 4 = 11
11 - 4 = 7
7 - 4 = 3
3 - 4 = - 1
- 1 - 4 = - 5

Answer:
32 years old
Step-by-step explanation:
Let Ale's age be x years old today.
Theo's age= x+10
In 4 years ,
Ale's age= x+4
Theo's age= x+10+4= x+14
Sum of their age= 82
x+4 + x+14= 82
2x +18= 82 (Simplify)
2x= 82 -18 (bring constant to 1 side)
2x= 64 (simplify)
x= 64 ÷2
x= 32
Thus, Ale is 32 years old today.
