14​

Answer 1

Answer:

First three terms are 5,6, and 7.

Step-by-step explanation:

Given:

24th term=2×10th term

a+23d=2(a+9d)

a+23d=2a+18d

23d-18d=2a-a

5d=a-----------☆

Also,

6th term=10

a+5d=10-----♡

From ☆ and ♡

a+a=10

2a=10

a=10/2

a=5.

a=5d

5=5d

5/5=d

1=d

d=1.

1st term=a=5

2nd term=a+d=5+1=6

3rd term=2nd term+d=6+1=7

First three terms are:

5,6, and 7
