Q. Type the missing number in this sequence:23, _, 43, 53, 63, 73, 83
Determine Pattern: We need to determine the pattern in the sequence to find the missing number. Let's look at the difference between the numbers that are given.
Calculate Differences: The difference between 43 and 53 is 10, between 53 and 63 is also 10, and this pattern continues for the rest of the sequence. This suggests that the sequence increases by 10 each time.
Subtract to Find Missing Number: If we subtract 10 from 43, we should get the missing number in the sequence. Let's perform the subtraction: 43−10=33.
Verify Solution: The missing number in the sequence is 33. We can check this by ensuring that adding 10 to 33 gives us the next number in the sequence, which is 43: 33+10=43.
