yn = 1/2n2 + 2 1/2n + 3
y9 = 1/2(9)2 + 2 1/2(9) + 3
y9 = 40 1/2 + 22 1/2 + 3
y9 = 66
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.
is this question number 10? 4n - 1 creates the pattern 3, 7, 11, 15, 19, etc.
21: (3)+3=(6)+4=(10)+5=(15)+6=(21)
45
there is not much of a pattern there but i would say 45
Each consecutive number is being divided by 10
5+5 = 10 10+5 = 15 15-5 = 15 10+5 = 15
What would be the next number in this series 15 12 13 10 11 8?
15. 5 - -10 = 5 + 10 = 15 → 15 + -10 = 15 - 10 = 5
The rule is 5, 10, 15 and so the next number will be 20+31 = 51
you add 10 to each number in the series of three. If you break the pattern into groups of three you will see 8-14-5 then 18-24-15 then 28-34. . . so 8+10=18+10=28, 14+10=24+10=34, 5+10=15+10=25, so continuing the pattern would be starting at 28: 28-34-25-38-44-35-48-54-45. . .
(5x10)9 =1.953125 E15 this means it is a very larger number the decimal is 15 places to the right aka to large for an average calculator
