![]() You will not find the common difference of this sequence. The common difference is eight and we will also have to denote that N is greater than or equal to do because this recursive formula Is applicable mainly when N is greater than or equal to two. So we can basically replace this formula to find the recursive formula. So formal law, we can replace this form rather this IAN equals a n minus one plus the common difference D. That is we have to find the recursive formula. So it is eight times of 39 and we can Multiply eight with 30 names. Always do the operation inside the parenthesis first, then multiply the result by the number outside the parenthesis( this is the common difference). ![]() Find 40 Given the first term and the common difference of an arithmetic sequence find explicit rule and the 37thterm. ![]() In the formula given above: -tn is the nth term -n is the terms number in the sequence. For each arithmetic sequence, find the term named in the problem, the explicit formula, and the recursiveformula. So therefore this becomes 17 plus eight times off We replaced then by that line. To find the explicit formula for an arithmetic sequence you must use the formula tn a+ (n - 1)d. So this is part one and it's answered the part two. So therefore the common difference of this arithmetic sequences. So this equals 33 -25 And this is equal to eight. This equals the difference between these two terms. Now the common difference indicated by letter D. So this becomes 17 times 17 plus eight times of two. I'm now going to find the the consecrated term. So therefore this becomes 17-plus 8 times of one. one In this formula, that is equal to one. So to find the common difference, I'm going to first to find a one. Remember that? The common difference is the difference obtained Between any two constituted terms in an arithmetic sequence. Let's now determine the common difference of this arithmetic sequence.
