Here is a number sequence. 31 26 21 16
11...
What is the first negative term in the sequence?
(1 mark)

Step-by-step explanation:

A sequence is given to us . And we need to find the first negative term of the sequence. So the given sequence to us is :-

Here first term of the sequence is 31. And the common difference is 26 - 31 = -5 . Hence here (-5) is added to each number to obtain the second number of the sequence .

Here the last term mentioned is 16. And we are subsequently adding (-5) to each term to obtain the next term . Next third term will be obtained after adding 5×(-3) = -15 .

And that term will be , 16 - 15 = 1 .

Hence the last positive term is 1 . The next term term after adding (-5) will be the first negative term.

26
