First Five Terms of Arithmetic Sequence: Use the given conditions or values and the general term of an arithmetic sequence to compute the common difference between the terms, then plug the values of the first term, common difference, and the termnin...
Answer to: List the first five terms a_1, a_2, a_3, a_4, and a_5 of the sequence: a_n = {4 (-1)^n} / {n!}. By signing up, you'll get thousands of...
Step 5: Calculate the fourth termNext, we find the fourth term:a4=a3−3Substituting a3=−2:a4=−2−3=−5 Step 6: Compile the first four termsNow we can compile the first four terms of the sequence:a1=1,a2=0,a3=−2,a4=−5 Thus, the first four terms of the sequence...
