In the following question, choose the one option which is similar to the given set

Given Set : (21, 91, 35)

(21, 51, 15)

(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)
