Concept:The sequence increases by a pattern of consecutive natural numbers added to each term.From 11 to 16, the increase is 5. From 16 to 22, the increase is 6.So the differences are 5,6,7,8,9,10.Explanation:Write the given terms: 11,16,22,29,−,46,56.Find the differences between consecutive known terms:16−11=522−16=629−22=7Next difference should be 8.So the missing number is 29+8=37.Check the next step: 46−37=9Then 56−46=10.This matches the pattern of differences increasing by 1 each time.Answer:The missing number is 37.Correct option: C. 37.
