According to the question:
n = 50
a3 = 12
a + 2 * d = 12 -(1)
a50 = 106
a + 49 * d = 106 -(2)
After solving (1) and (2) you will get
47 * d = 106 – 12
d = 94/47 = 2
and a = 12 -4 = 8
So, a29 = a + 28 * d
a29 = 8 + 28 * 2
a29 = 64
So the 29th term of the given A.P. will be 64.

Answer:
a4=0
Step-by-step explanation:
an=50
a=4
AP=4,-8
d=-4
a1=4, a2= -8 a3=a2+d= -8+4
=-4
a4=a3+d
=-4+ -4 =0
hope it is helpful
