Arithmetic Progression

In an Arithmetic Progression, if a = 28, d = -4, n = 7, then a_n is:

• 4

• 5

• 7

• 3

If a = 10 and d = 10, then first four terms will be:

• 10, 15, 25, 30

• 10, 20, 50, 60

• 10, 20, 30, 40

• 10, 18, 20, 30

The first term and common difference for the A.P. 3, 1, -1, -3 is:

• 1 and -3

• 2 and 3

• 3 and -2

• 1 and 3

30th term of the A.P: 10, 7, 4, …, is

• 77

• 87

• -77

• 97

11th term of the A.P. -3, -1/2, 2 …. is:

• 22

• 12

• -12

• 28

The sum of the first five multiples of 3 is:

• 75

• 65

• 55

• 45

The number of multiples of 4 between 10 and 250 is:

• 30

• 40

• 50

• 60

Which term of the A.P. 3, 8, 13, 18, … is 78?

• 11th term

• 14th term

• 16th term

• 20th term

The missing terms in AP: , 13, , 3 are:

• 11 and 9

• 17 and 9

• 18 and 9

• 18 and 8

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

• an AP with d = -16

• an AP with d = 4

• an AP with d = -4

• not an AP
