[The answer is in bold]
The 90th term of the AP can be found by using the formula
=> a + (n - 1)d
Where a is the First term of the AP, n is the unknown term's position and d is the common difference [Succeeding term - preceding term].
Here, n is 90. So the 90th term of your AP will be a + 89d.
You just need the values of a and d for the answer. Try it out. Take NCERT and do its excercise. You'll find it very easy. AP is a nice chapter isn't it?
