Q. Type the missing number in this sequence:0, 0, 2, 6, _____, 20, 30, 42
Identify Pattern: Identify the pattern in the sequence.Looking at the differences between consecutive terms: 0−0=0, 2−0=2, 6−2=4.The differences are increasing by 2 each time.
Calculate Next Difference: Calculate the next difference and find the missing term.The next difference after 4 should be 6 (4+2).Adding 6 to the last known term (6) gives 12.
Verify Pattern Continues: Verify the pattern continues correctly after the missing term.Adding 8 to 12 gives 20, which matches the next term in the sequence.
