Q1 of 89 Page 45

In an AP, if d = - 4, n = 7 and a_n = 4, then a is equal to

As we know, nth term of an AP is

a_{n =} a + (n - 1)d

where a = first term

a_n is nth term

d is the common difference

4 = a + (7 - 1)(- 4) …..(Given Data)

4 = a - 24

a = 24 + 4 = 28

In an AP, if a = 3.5, d = 0 and n = 101, then a_n will be

The list of numbers – 10, - 6, - 2, 2, … is

The 11^th term of an

The first four terms of an AP whose first term is - 2 and the common difference is - 2 are

In an AP, if d = - 4, n = 7 and an = 4, then a is equal to
