AS - sequence

What are the first ten members of the sequence if a11=22, d=2.

Result

a10 =  20
a9 =  18
a8 =  16
a7 =  14
a6 =  12
a5 =  10
a4 =  8
a3 =  6
a2 =  4
a1 =  2

Solution:

a10=222=20a_{10}=22-2=20
a9=202=18a_9=20-2=18
a8=182=16a_8=18-2=16
a7=162=14a_7=16-2=14
a6=142=12a_6=14-2=12
a5=122=10a_5=12-2=10
a4=102=8a_4=10-2=8
a3=82=6a_3=8-2=6
a2=62=4a_2=6-2=4
a1=42=2a_1=4-2=2
