Answer:-37 is the first positive term I think so…

Answer:Thirteenth term

Step-by-step explanation:As we know that the moment the term is zero the very next term will be positive

Thus

We know that

1 = -45 + (n – 1)(4)

46 = (n – 1)(4)

n – 1 = 46/4

Since it is in fraction which means 1 is not the positive term

Now we will try with 2 and so on until the value of n comes in a whole number

Lets try with 3 this time

We know that

3 = – 45 + (n – 1)(4)

3 + 45 = (n – 1)(4)

48/4 = n-1

12 = n – 1

n = 13

Thus thirteenth term of this AP will be a positive term

I hope this helps you……….
