Question

Find the number of terms in the following sequence.

Answer 1

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
