the 1st term of an ap is twice the common difference find in terms of the 5th term of the ap

• maths -

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
