Find the next term in the series: 6, 12, 11, 22, 21, 42, 41, ?
Alternating series: ×2, -1. Next operation gives 82
alternating, operations

Question 2

Find the next term in the series: 13, 15, 45, 47, 141, 143, ?
Alternating series: +2, ×3. Next operation gives 429
alternating, operations

Question 3

Find the next term in the series: 6, 7, 10, 15, 22, 31, ?
The differences between terms increase by 2 each time. Last difference was 9, next difference is 11, so next term = 31 + 11 = 42
difference, pattern

Question 4

Find the next term in the series: 4, 6, 8, 18, 16, 54, 32, 162, ?
Two alternating geometric series: First: ×2, Second: ×3. Next follows second pattern: 32 × 3 = 96
alternating, arithmetic

Question 5

Find the next term in the series: 8, 11, 15, 20, 26, 33, ?
The differences between terms increase by 1 each time. Last difference was 7, next difference is 8, so next term = 33 + 8 = 41
difference, pattern

Question 6

Find the next term in the series: 9, 14, 21, 30, 41, 54, ?
This is a series of consecutive perfect squares plus 5: (2²+5), (3²+5)... Next term = 8² + 5 = 69
perfect, squares

Question 7

Find the next term in the series: 13, 14, 16, 19, 23, 28, ?
The differences between terms increase by 1 each time. Last difference was 5, next difference is 6, so next term = 28 + 6 = 34
difference, pattern

Question 8

Find the next term in the series: 0, 3, 8, 15, 24, 35, ?
This is a series of consecutive perfect squares minus 1: (1²-1), (2²-1)... Next term = 7² - 1 = 48
perfect, squares

Question 9

Find the next term in the series: 7, 17, 47, 137, ?
Each term follows: (previous term × 3) - 4. Next term = (137 × 3) - 4 = 407
multiplication, addition

Question 10

Find the next term in the series: 3/6, 3/7, 3/8, 3/9, 3/10, 3/11, ?
The denominator increases by 1 each time while numerator remains 3. Next term = 3/12
fraction, pattern

Question 11

Find the next term in the series: 25, 36, 49, 64, ?
This is a series of consecutive perfect squares: 5², 6², 7²... Next term = 9² = 81
perfect, squares

Question 12

Find the next term in the series: 1, 9, 17, 25, 33, 41, ?
This is an arithmetic series with common difference 8. Next term = 41 + 8 = 49
arithmetic, progression

Question 13

Find the next term in the series: 383, 393, 404, 414, 424, ?
This is a series of palindromic numbers (numbers that read the same forwards and backwards). The next palindrome after 424 is 434
palindrome, numbers

Question 14

Find the next term in the series: 13, 12, 36, 35, 105, ?

alternating, operations

Question 15

Find the next term in the series: 393, 404, 414, 424, ?
This is a series of palindromic numbers (numbers that read the same forwards and backwards). The next palindrome after 424 is 434
palindrome, numbers

Question 16

Find the next term in the series: 8, 13, 20, 29, 40, 53, ?
This is a series of consecutive perfect squares plus 4: (2²+4), (3²+4)... Next term = 8² + 4 = 68
perfect, squares

Question 17

Find the next term in the series: 1, 5, 3, 9, 17, ?
This is a Tribonacci series where each term is the sum of the previous three terms. Next term = 17 + 9 + 3 = 29
fibonacci, recursive

Question 18
