42 40 38 35 33 31 28 A. 25, 22 B. 26, 23 C. 26, 24 D. 25, 23
Here in given series
42-40=2
40-38=2
38-35=3
35-33=2
33-31=2
31-28=3
Thus it is clearly visible that the sequence is an alternating subtraction series in which 2 is subtracted twice followed by subtracting 3 once and then following the similar pattern.
Thus we get the next two number as.
28-2=26
26-2=24
Therefore the answer is 26,24 option C
