Answer:
a= -18(first number)
d= 2 (common difference ) (a2-a1)
10th term = a10= a+(n-1)d
-18+(10-1) 2= -18+18=0
so, AP of 10th term is 0.
Step-by-step explanation:
t10 = a + (n-1)d ----> formula
a = -18
d = -16-(-18) = 2
t = (-18)+(10-1)(2)
= (-18)+(18)
= -18+18
= 0 ..
therefore, the tenth term of A.P is 0 ..:);)
