Week Minutes of Practice
1 30
2 40
3 52
4 66
5 82
6 ?

If Morris continues to follow this pattern, how many minutes will he practice playing the trumpet during Week 6?
A.
100
B.
99
C.
98
D.
101

Respuesta :

40-30=10
52-40=12
66-52=14
82-66=16

Each time the difference between two consective weeks gains two minutes, so if the difference between weeks 5 and 4 is =16 minutes then we add two minutes

16+2=18

Then we add the previous time to 18

18+82=100
Week 6 = 100 minutes

So the answer is A. 100
