Select the correct option that will fill in the blank and complete the series. 3, 5, 7, 9, 11, ? 2, 2, 2, 2, 2, ?
13, 2
Observe the difference between consecutive terms in the first series:
The pattern is an arithmetic progression with a common difference of 2. To find the missing term, add 2 to the last term:
Next term = $11 + 2 = 13$
Observe the difference between consecutive terms in the second series:
This is a constant sequence where each term is 2. The common difference is 0. To find the missing term, add 0 to the last term:
Next term = $2 + 0 = 2$
The missing terms for the two series are 13 and 2, respectively. This corresponds to option C.
