Needed the full question
18, 57, 5, 92, 7, 67
What comes next?
10 or 22?
Why?
Answer is ……..TEN
Spell out the numbers and 10 comes before 22 in alphabetical order.
(i.e. eighteen, fifty seven, five, ninty two, seven, sixty seven, ten, twenty two)
The difference between one number and the next in the sequence is decreasing by 9 each time. Therefore, the difference between -4 and the next number will be equal to 62 - 9 = 53. The next number is therefore equal to -4 - 53 = -57.
174 =============== 18 = 15+3 54 = 18x3 57 = 54+3 171= 57x3 174= 171+3
The pattern is add three and then multiply by three. The next number is 174.
57
the next two are 174 and 522.
21
1 + 71 = 8 8 + 72 = 57 57 + 73 = 400 400 + 74 = 2801
57
The difference between each number is decreasing by 1 each time. Therefore, the difference between the final number and the next number in the sequence will be 6. Therefore, 50 - 6 = 44.
37: How? Every time a new number is put into the sequence, when you subtract it from the number before it, it will equal an odd number of greater value. For example; 72-69=3 69-64=5 64-57=7 57-48=9 48-37=11
The difference between one number and the next in the sequence is decreasing by 9 each time. Therefore, the difference between -4 and the next number will be equal to 62 - 9 = 53. The next number is therefore equal to -4 - 53 = -57.
174 =============== 18 = 15+3 54 = 18x3 57 = 54+3 171= 57x3 174= 171+3
The pattern is add three and then multiply by three. The next number is 174.
It is a quadratic sequence (order 2) t(n) = (9n2 - 205n + 792)/2 for n = 1, 2, 3, ... and the next number is -57
