Given :- Find the alternative set of the given questions :
(i) (11, 24,50)
(i) (7, 15, 31)
(iii) (13, 28, 57)
(iv) (21,44,90)
Solution :-
Pattern in (i) :- 11, 24, 50 .
→ 11 * 2 + 2 = 22 + 2 = 24 .
→ 24 * 2 + 2 = 48 + 2 = 50.
Pattern in (ii) :- 7, 15, 31 .
→ 7 * 2 + 1 = 14 + 1 = 15 .
→ 15 * 2 + 1 = 30 + 1 = 31.
Pattern in (iii) :- 13, 28, 57 .
→ 13 * 2 + 2 = 26 + 2 = 28 .
→ 28 * 2 + 1 = 56 + 1 = 57.
Pattern in (iv) :- 21, 44, 90 .
→ 21 * 2 + 2 = 42 + 2 = 44 .
→ 44 * 2 + 2 = 88 + 2 = 90.
