Both numerator and denominator increase by 1 each time. Next term = 6/8

fraction, pattern

Question 2

Find the next term in the series: 41, 43, 47, 53, 59, ?

This is a series of consecutive prime numbers. The next prime after 59 is 61

This is a series of consecutive prime numbers. The next prime after 139 is 149

prime, numbers

Question 5

Find the next term in the series: 2, 6, 24, 120, 720, ?

This is a factorial series: 2!, 3!, 4!... Next term = 7! = 5040

factorial, growth

Question 6

Find the next term in the series: 7, 28, 112, 448, 1792, ?

This is a geometric series with common ratio 4. Next term = 1792 × 4 = 7168

geometric, progression

Question 7

Find the next term in the series: 191, 202, 212, 222, 232, ?

This is a series of palindromic numbers (numbers that read the same forwards and backwards). The next palindrome after 232 is 242

palindrome, numbers

Question 8

Find the next term in the series: 9, 16, 12, 19, 15, 22, 18, 25, ?

Two alternating arithmetic series: First: +3, Second: +3. Next follows second pattern: 18 + 3 = 21

alternating, arithmetic

Question 9

Find the next term in the series: 12, 15, 20, 27, 36, ?

The differences between terms increase by 2 each time. Last difference was 9, next difference is 11, so next term = 36 + 11 = 47

difference, pattern
