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
