Number Sequence Logic
The sequence given is 4, 9, 19, 39, 79, ?. We need to find the missing term.
Let's analyze the pattern by comparing consecutive terms:
- The second term is $9$. $9 = (4 \times 2) + 1$.
- The third term is $19$. $19 = (9 \times 2) + 1$.
- The fourth term is $39$. $39 = (19 \times 2) + 1$.
- The fifth term is $79$. $79 = (39 \times 2) + 1$.
The pattern identified is: multiply the previous term by 2 and add 1 to get the next term.
To find the missing term (?), we apply this pattern to the last term (79):
Missing Term $= (79 \times 2) + 1$
Missing Term $= 158 + 1$
Missing Term $= 159$
Thus, the number 159 should come at the place of the question mark.
