Question

If the 1st term of an ap is twice it common difference find the 5th term of the sequence in term of common difference

Answer 1

Step-by-step explanation:

a = 2d

term1 = 2d

term2 = a+d = 2d+d = 3d

term3 = a + 2d = 2d + 2d = 4d

term4 = 5d

term5 = 6d

etc

so you can let d be any value, say d= 5

then the 5 terms are

10 15 20 25 30

if d = 17

terms are 34 51 68 85 102

Answer 2

Answer:

Let

a be the first term

and

ATQ

a = 2d

d be the common difference

a5 = a + [n -1)d

=2d + nd -d

=d+nd

this is ur answer buddy
