Determine 2937

Determine the first 14 members of the sequence if a15 = 225, d = -12

Correct answer:

a14 =  237
a13 =  249
a12 =  261
a11 =  273
a10 =  285
a9 =  297
a8 =  309
a7 =  321
a6 =  333
a5 =  345
a4 =  357
a3 =  369
a2 =  381
a1 =  393

Step-by-step explanation:

a15​=225 d=−12 a14​=a15​−d=225−(−12)=237
a13​=a14​−d=237−(−12)=249
a12​=a13​−d=249−(−12)=261
a11​=a12​−d=261−(−12)=273
a10​=a11​−d=273−(−12)=285
a9​=a10​−d=285−(−12)=297
a8​=a9​−d=297−(−12)=309
a7​=a8​−d=309−(−12)=321
a6​=a7​−d=321−(−12)=333
a5​=a6​−d=333−(−12)=345
a4​=a5​−d=345−(−12)=357
a3​=a4​−d=357−(−12)=369
a2​=a3​−d=369−(−12)=381
a1​=a2​−d=381−(−12)=393
