Question

If the sum of 3rd and 8th term of an ap is 7 and sum of 7th and 14th term is-3 find the 10th term

Answer 1

Hey mate..

Here is your answer...

ATQ,

a + 2d + a + 7d = 7

2a+9d=7 ------(1)

And,

a+ 6d+a+13d= - 3

2a+19d= - 3 -------(2)

Subtract eq. 1 from 2

10d= - 10

d= - 1

So,

a=8

10th term=a+9d = 8+9(-1)=8-9=-1

HOPE that it will help you ✌️ ✌️
