Question

2
The
missing terms
in AP : – , 13, –, 3 are?

​

Answer 1

Answer:

We have to find the common difference first. for that we have:

term difference = position difference * common difference(d)

in this case, (3-13) = (4-2)*d

-10 = 2*d

d = -10/2

d = -5

so the first term = 13-(-5) = 13+5 = 18

3rd term = 13-5 = 8
