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=a15d=225(12)=237
a13=a14d=237(12)=249
a12=a13d=249(12)=261
a11=a12d=261(12)=273
a10=a11d=273(12)=285
a9=a10d=285(12)=297
a8=a9d=297(12)=309
a7=a8d=309(12)=321
a6=a7d=321(12)=333
a5=a6d=333(12)=345
a4=a5d=345(12)=357
a3=a4d=357(12)=369
a2=a3d=369(12)=381
a1=a2d=381(12)=393
