the common difference was 1 (one) and the next three terms are 5,6,7.... just add one to the number to get the next number.. hoping to answer this question correct..
to find the common difference is just subtract the second no. to 1st no. , d= 2-1 d=1 now that the difference is 1 , just add one to the corresponding no. therefore, the answers are 5,6, and 7
