Question

Find the 15th term of arithmetic progression 6 .10.14 using the formula

Answer 1

Answer:

62

Step-by-step explanation:

The AP is 6, 10, 14.
It can be clearly seen that
a = 6 and d = 10 - 6 = 4
Now we know the formula,
an = a + (n - 1)d
    = 6 + (15 - 1)*4
    = 6 + 14 * 4
     = 6 + 56
    =  62
