Answer 1

SOLUTION

TO DETERMINE

The term of the AP which is 78 for the AP

3 , 8 , 13 , 18 ,....

EVALUATION

Here the given arithmetic progression is

3 , 8 , 13 , 18 ,....

First term = a = 3

Common Difference = d = 8 - 3 = 5

Let n th term of the AP = 78

So by the given condition

$\sf{a + (n - 1)d = 78}$

$\sf{ \implies \: 3 + 5(n - 1) = 78}$

$\sf{ \implies \: 5(n - 1) = 75}$

$\sf{ \implies \: (n - 1) = 15}$

$\sf{ \implies \: n = 16}$

FINAL ANSWER

Hence the 16 th term of the AP = 78
