Answer:
Formula for the nth term of an A.P. :
tn = a + ( n - 1 ) d
Step - by - step explanation:
Generally, in the A. P. t1, t2, t3,...... if the first term is 'a' and the common difference is 'd',
t1 = a
t2 = t1 + d = a + d = a + ( 2 - 1 ) d
t3 = t2 + d = a + d + d = a + 2d = a + ( 3 - 1 ) d
t4 = t3 + d = a + 2d + d = a + 3d = a + ( 4 - 1 ) d
∴ we get the formula
tn = a + ( n - 1 ) d
