Answer:
50, 48, 46, 44,.....
a = 50 and d = 48 - 50 = -2
Let tn be the first negative term.
tn < 0
a + (n - 1)d < 0
50 + (n - 1)(-2) < 0
Solving we get n > 26
So, 27th is the first negative term in the given sequence.
According to the question S26 is the maximum sum of the gien sequence.
Find S26 using a = 50, n = 26 and d = -2 we get S26 = 650
