Answer:

-16

Explanation:

Given that the first term is -10 .

=> a1 = -10 .

General formula:-

=> a_n = a_n -1 + 3 .

Therefore , the common difference :-

=> 2nd term - 1 term

=> a_n-1 - a_n = -3

nth term of the AP is ,

=> T_n = a + (n-1)d

=> T_3 = -10 + (3-1) × -3

=> T_3 = -10 + -6

=> T_3 = -16 .
