Question

If in an A.P d=10 find t6-t2

Answer 1

Hey mate here is your answer @@@@
A.P is a sequence of numbers
here , d = 10
to find :: t6 - t2
Solution ::: tn = a + ( n - 1 ) * d ...........( formula )
t2 = a + ( 2 - 1 ) * 10
t2 = a + 10 .....................(1)
Now ,, tn = a + ( n - 1 ) * d ..............(formula)
t6 = a + ( 6 - 1 ) * 10
t6 = a + 50 ......................(2)
Now subtract (1) and (2) equations
a+ 60 - a + 10 = t6 - t2
70 = t6 - t2 ......(3)

Answer " t6 - t2 = 70 ........... from (1) , (2) and (3)
