Answer:
the 16th term!!!
Step-by-step explanation:
if the first # is 20 and the common difference is -6 the 16th term would be -70
Step-by-step explanation:
The term 16 has the value of -70
because when
Un=-70 , a=20, d=-6, n=??
Un= a+(n-1)d
-70=20+(n-1)-6
-70=20-6n+6
6n=20+6+70
6n=96, divide both sides by 6
∴ the 16 term has the value of -70
