What is the 103rd term of the arithmetic sequence

option B: 31/4

Step-by-step explanation:

Given

-3/4, -2/3 , -7/12, -1/2...........

General formula for arithmeti sequence to find nth term is

a_n = a_1 + (n-1) d

first term a_1 = -3/4

We find out common difference 'd'

Lets find the difference of first two terms

common difference is 1/12

now we need to find 103rd term

First term is -3/4, d= 1/12

ans: B: 31/4   is the 103rd term of the arithmetic sequence
