Step-by-step explanation:

a=42 d=21 an=210.

a=42 d=21 an=210.an=a+(n-1)d

a=42 d=21 an=210.an=a+(n-1)d 210=42+(n-1)21

a=42 d=21 an=210.an=a+(n-1)d 210=42+(n-1)21210=42+21n-21

a=42 d=21 an=210.an=a+(n-1)d 210=42+(n-1)21210=42+21n-21210=21+21n

a=42 d=21 an=210.an=a+(n-1)d 210=42+(n-1)21210=42+21n-21210=21+21n210-21=21n

a=42 d=21 an=210.an=a+(n-1)d 210=42+(n-1)21210=42+21n-21210=21+21n210-21=21n 189=21n

a=42 d=21 an=210.an=a+(n-1)d 210=42+(n-1)21210=42+21n-21210=21+21n210-21=21n 189=21n189/21=n

a=42 d=21 an=210.an=a+(n-1)d 210=42+(n-1)21210=42+21n-21210=21+21n210-21=21n 189=21n189/21=n9=n
