A number pattern is quadratic when which of these is constant?
For the pattern \(-7 \,;\, 0 \,;\, 9 \,;\, 20 \,;\, \ldots\) the second difference is:
The general term of \(-7 \,;\, 0 \,;\, 9 \,;\, 20 \,;\, \ldots\) is:
Which term of \(-7 \,;\, 0 \,;\, 9 \,;\, 20 \,;\, \ldots\) equals \(128\)?
The general term of the FIRST differences of \(-7 \,;\, 0 \,;\, 9 \,;\, 20 \,;\, \ldots\) is:
