AS - sequence

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

Correct answer:

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

Step-by-step explanation:

a11​=22 d=2  a10​=a11​−d=22−2=20
a9​=a10​−d=20−2=18
a8​=a9​−d=18−2=16
a7​=a8​−d=16−2=14
a6​=a7​−d=14−2=12
a5​=a6​−d=12−2=10
a4​=a5​−d=10−2=8
a3​=a4​−d=8−2=6
a2​=a3​−d=6−2=4
a1​=a2​−d=4−2=2
