Question

Which term of the



a.P 84,80,76,72....Will be the first negative number?

Answer 1

I think there will be no negative number.

Answer 2

Every time it goes down by four.

If 84 (= 88 - 4) is the first term, then the easiest way to set up for the (n)th term is:

88 - 4n

When will that be 0?

88 - 4n = 0

You can finish.

Best wishes!
