First, find the common difference.a_2-a_1=5-(5+k) or -k find the difference between pairs of consecutive termsa_3-a_2=5-k-5 or -k to verify the common difference.The common difference is -k.Add -k to the third term to get the fourth term, and so on.a_4=5-k-k or 5-...
Identify the common difference in the arithmetic sequence: 13, 20, 27, 34, ... Find the common difference in the following arithmetic sequence. x + 1, x + 4, x + 7, x + 10, ... Find the common difference in the following arithmetic sequence. ...
A series of numbers in which the difference of two successive numbers is always constant, known as the arithmetic sequence, and this constant difference is known as the common difference. So to check a sequence for arithmetic, it is necessary to find out the ...
Common difference ( d ) which is calculated as d = a2– a1= a3– a2= ……. = an– an – 1 the nth term of the arithmetic sequence Sum of first n terms ( Sn) The arithmetic sequence can also be written in terms of common difference, as follows – ...

The 7-th term of the arithmetic sequence is: 23 Explanation:In the above exercise -The "findNthTermArithmetic()" function takes three parameters: x (the first term of the sequence), d (the common difference), and n (the term number to find). The function uses recursion to find the...
6. Check if the sequence is an A.P.: To determine if the sequence is an A.P., we need to check if the common difference is constant. - Calculate the common difference D1 between the first and second terms: D1=T2−T1=17−5=12 - Calculate the common difference D2 between the...
