Question

which term of AP 124 119 104..... find the negative term​

Answer 1

First term of given Arithmetic progression = 124

Common difference = -5
Now,
Let's consider that we want to find which term will be zero in the given arithmetic progression.

So,
Tn = a + (n-1) d

Therefore,

0 = 124 + (n-1)(-5)
124/5 = n-1
n= 129/5

So, obviously a term number cannot be a fraction, so that means obviously 0 isn't a term of the given arithmetic progression

However, the first negative term will be just the next integer value of n=129/5 because the arithmetic progression is a decreasing one !

So,
129/5 = 25 + 4/5
So, the first negative term will be the 26th term


Hope this helps you ! ^_^
