Sequence

Write the first 7 members of an arithmetic sequence: a1=-3, d=6.

Correct result:

a1 =  -3
a2 =  3
a3 =  9
a4 =  15
a5 =  21
a6 =  27
a7 =  33

Solution:

a1=3a_1 = -3
a2=a1+6=3a_2 = a_1+6 = 3
a3=a2+6=9a_3 = a_2+6 = 9
a4=a3+6=15a_4 = a_3+6 = 15
a5=a4+6=21a_5 = a_4+6 = 21
a6=a5+6=27a_6 = a_5+6 = 27
a7=a6+6=33a_7 = a_6+6 = 33
