In the following question, choose the one option which is similar to the given set
Given Set : (21, 91, 35)
Answer & explanation
Correct answer: option 3
(21, 91, 35)
Pattern followed here is :-
( 3rd term × 2 ) + 1st term = 2nd term
( 35 × 2 ) + 21 = 91
70 + 21 = 91
91 = 91
Similarly ,
(21, 51, 15)
Pattern followed here is :-
( 3rd term × 2 ) + 1st term = 2nd term
( 15 × 2 ) + 21 = 51
30 + 21 = 51
51 = 51
The correct answer is Option (3) → (21, 51, 15)
