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
