3, 5, 7, 6, 10, 14, 12, 24, 28, 24, 40, 56
Solution
The Given series 3, 5, 7. 6, 10, 14, 12, 24, 28, 24, 40, 56
the number in 3 -3 pairs and multiple 2 and give the next pairs
(3,5,7) (6, 10, 14) (12, 24, 28) (24, 40,56)
then $$(3,5,7) \times 2 = (6,10,14) $$
next $$(6,10, 14) \times 2 = (12,20, 28) $$
therefore in the third pairs 24 is incorrect correct number 20
hence our and = 24
