Use the formula for the general term​ (the nth​ term) of an arithmetic sequence to find the sixth term of the sequence with the given first term and common difference.

a1 =15; d=7

a6 =

Solutions

Expert Solution

an = a1 + (n - 1)d                                                                                                          

a6 = a1 + (6 - 1)d = 15 + 5 * 7 = 50 (ans)
