Question 1

Find the next term in the series: 99, 101, 111, 121, 131, ?
This is a series of palindromic numbers (numbers that read the same forwards and backwards). The next palindrome after 131 is 141
palindrome, numbers

Question 2

Find the next term in the series: 272, 282, 292, 303, ?
This is a series of palindromic numbers (numbers that read the same forwards and backwards). The next palindrome after 303 is 313
palindrome, numbers

Question 3

Find the next term in the series: 4, 7, 11, 18, 29, 47, 76, ?
Each term is the sum of the previous two terms. Next term = 76 + 47 = 123
fibonacci, recursive

Question 4

Find the next term in the series: 15, 30, 15, 30, 15, 30, 15, ?
Alternating series: multiply by 2, divide by 2. Next operation gives 30
alternating, operations

Question 5

Find the next term in the series: 4, 2, 6, 12, 20, 38, ?
This is a Tribonacci series where each term is the sum of the previous three terms. Next term = 38 + 20 + 12 = 70
fibonacci, recursive

Question 6

Find the next term in the series: 8, 20, 50, 125, ?
This is a geometric series with common ratio 2.5. Next term = 125 × 2.5 = 312.5
geometric, progression

Question 7

Find the next term in the series: 7, 21, 63, 189, ?
This is a geometric series with common ratio 3. Next term = 189 × 3 = 567

palindrome, numbers

Question 9

Find the next term in the series: 27, 81, 243, 729, 2187, ?
This is an exponential series with base 3: 3^3, 3^4, 3^5... Next term = 3^8 = 6561
exponential, growth

Question 10

Find the next term in the series: 14, 17, 23, 32, 44, ?
The differences between terms increase by 3 each time. Last difference was 12, next difference is 15, so next term = 44 + 15 = 59
difference, pattern
