Attempt following question by selecting a choice to answer.
D
If 4 is the common difference of the arithmetic sequence
a1, a2, a3, ... and 24 is the common difference for the arithmetic sequence
b1, b2, b3, ... , then the common difference for the arithmetic sequence
a1 + b1, a2 + b2, a3 + b3, ... is:BB DDA.

A
Step 1: 4 = a2 - a1[Common difference for the 1st sequence.]
Step 2: 24 = b2 - b1[Common difference for the 2nd sequence.]
Step 3: d = (a2 + b2 ) - (a1 + b1 )[Formula for common difference.]
Step 4: d = (a2 - a1) + ( b2 - b1 )
Step 5: = 4 + 24 = 28
