The first term of an AP is -7 and the ratio of the eight term to the third term is 7:1 calculate the common difference

the common difference is 6.

Step-by-step explanation:

Given;

first term of an AP, a = -7

let the common difference = d

The third term is written as;

T₃ = a + 2d

The eight term is written as;

T₈ = a + 7d

The ratio of the eight term to third term = 7:1

Therefore, the common difference is 6.

-3.396 = -3.4

-0.708 = -0.7

0.304 = 0.3

0.955 = 1

36
