The answer is 58
The Next NumberThe next number is 25 if you use the following pattern: 5, (the number 10), 15 (the first number +10), (the number 10), and the next number is the third number +10 or 25.or you could think of it this way:5, 10 (+5), 15 (+5), -5 (10)The pattern is +5, +5, -5, so the next number would be 15, the next 20, and the next 15.
5 10 15 10 5
5+5 = 10 10+5 = 15 15-5 = 15 10+5 = 15
15 − 5 = 10Therefore the number is 15
