Determine wheather each set of the numbers is a sequence 3,18,33,48,

all of them are sum by 15

Step-by-step explanation:

3 + 15 = 18 + 15 = 33 + 15 = 48

the answer is 62

answer: first option i.e. 'a' is correct.

step-by-step explanation:

so, it becomes,

hence, first option 'a'   is correct.
