    Question

    The 10th term of the Arithmetic Progression 2, 7, 12, ... is :

    A.

    27

    B.

    47

    C.

    37

    D.

    57

    Correct option is B

    Given:

    An Arithmetic Progression (A.P.): 2, 7, 12,…

    We are to find the 10th term.

    Formula Used:

    The nth term of an A.P. is given by:

    an=a+(n1)da_n = a + (n - 1)d​​

    Where:

    a = first term

    d = common difference

    n = term number

    Solution:

    Now,

    a = 2, d = 7 - 2 = 5

    Applying the formula;

    a10=2+9×5=2+45=47a_{10} = 2 + 9 \times 5 = 2 + 45 = 47​​
