Q. Complete the recursive formula of the arithmetic sequence4,22,40,58,…. b(1)=□b(n)=b(n−1)+□
Find First Term: To find the first term of the arithmetic sequence, we look at the first given term in the sequence.The first term is 4.
Find Common Difference: To find the common difference, we subtract the first term from the second term.Common difference d = 22−4=18.
Check Consistency: We check if the common difference is consistent by subtracting subsequent terms.40−22 should also equal 18, and 58−40 should also equal 18.Let's check:40−22=18 and 58−40=18.The common difference is consistent.
Write Recursive Formula: Now we can write the recursive formula for the arithmetic sequence.The first term is b(1)=4.The recursive formula is b(n)=b(n−1)+18 for n > 1.
