Answer:
Oa: 141 correct option!
Step-by-step explanation:
33-(-9) =42
and 75-33= 42
clearly this is an Arithmetic progression with common difference=d=42
using (nth term = a+(n-1)d) {n is number of term,d is common difference and a is first term}
now, 5871 = -9+(n-1) 42
i.e, 5880=(n-1)42
i.e, n-1=140
i.e, n=141
