In the series 357, 363, 369, ….. what will be the 10th term ?
Correct
The given series is an A.P. in which a = 357 and d = 6.
∴ 10th term = a + (10 – 1) d = a + 9d
= (357 + 9 x 6) = (357 + 54 ) = 411.
Incorrect
The given series is an A.P. in which a = 357 and d = 6.
∴ 10th term = a + (10 – 1) d = a + 9d
= (357 + 9 x 6) = (357 + 54 ) = 411.

In the series 7, 14, 28, ….., what will be the 10th term ?
Correct
Clearly, 7 x 2 = 14, 14 x 2 = 28, ….. and so on.
So, the given series is a G.P. in which a = 7 and r =2 .
In each of the following questions, a number series is given with one term missing. Choose the correct alternative that will continue the same pattern and replace the question mark in the given series.
In the series 10, 17, 24, 31, 38, ….. which of the following will be a number of the series ?
Correct
The given series consists of numbers each of which, on dividing by 7, leaves a remainder 3. No other number except 346 satisfies the property.

Direction : In each of the following questions, one term in the number series is wrong. Find out the wrong term.
Direction : In each of the following questions, one term in the number series is wrong. Find out the wrong term.
121, 143, 165, 186, 209
Correct
Each term in the series is obtained by adding 22 to the preceding term.
So, 186 is wrong and must be replaced by (165 + 22) i.e. 187.
Incorrect
Each term in the series is obtained by adding 22 to the preceding term.
So, 186 is wrong and must be replaced by (165 + 22) i.e. 187.
