Q. Find the three terms in the sequence after the last one given1) 29,19,9,−1,…
Identify common difference: Identify the common difference in the sequence.The sequence given is 29,19,9,−1,…To find the common difference, subtract the second term from the first term:19−29=−10Check with another pair to confirm:9−19=−10The common difference is −10.
Calculate next three terms: Calculate the next three terms in the sequence using the common difference.The last term given is −1. To find the next term:−1−10=−11 (next term)Then, −11−10=−21 (second term after −1)Finally, −21−10=−31 (third term after −1)
