Question

Write the first ten terms of a sequence whose first term is -10 and whose common difference is -2.

Answer 1

Here is how your sequence will go:
n=-10
The next n would have a difference of -2 from the first n.
n_2 = -10-2=-12
The third n would have a difference of -2 from the second n.
n_3 = -12-2 = -14
And so on and so forth until you reach the tenth term.
