Which term in the number series is incorrect?

In following questions, one term in number series is incorrect. The numbers are 1 2 + 1, 2 2 + 1, 3 2 + 1 and so on. So, 64 is wrong. The correct term is (8 2 + 1) i.e. 65.

Is 8 27 125 125 343 1331 2197 an increasing series?

In the series 8, 27, 125, 343, 1331, 2197, we can see that it is an increasing series. The series is the cube of the consecutive prime numbers from 2 to 13. The table given below mentions a few other Quantitative Aptitude topics which candidates need to excel in to crack the upcoming bank exams.

How do you find the series of numbers 340 + 5 = 345?

The correct series is 49 + 0² = 49 + 1² = 50 + 2² = 54 + 3² = 63 + 4² = 79 + 5² = 104. Answer (c). 9, 9 x 2 = 18 + 1 = 19, 19 x 2 = 38 + 2 = 40, 40 x 2 = 80 + 3 = 83, 83 x 2 = 166 + 4 = 170 and 170 x 2 = 340 + 5 = 345. 340 should have been 345.

In following questions, one term in number series is incorrect. Each term is multiplied by 2 and then increased by 2 to obtain the next term. So, 64 is wrong and must be replaced by (30 * 2 + 2) i.e. 62.

What are the terms of the series?

Here we deal with the questions in which series of numbers, which are generally called the terms of the series is given. These terms follow a certain pattern throughout the series. Candidates are asked either to find a missing number or to find the one that does not follow the pattern of the series.

How do you know if a series is increasing or decreasing?

In the series 4, 8, 16, 32, 64, we can see that it is an increasing series and the series is increasing by the multiple of 2. In the series 100, 50, 25, 5, 1 we can see that it is a decreasing series and the series is decreasing as the terms are divided by 5.

Which number would you replace 41 with to satisfy the condition?

Replacing 41 with 42 would satisfy the condition. 126 – 28 = 98; 98 – 70 = 28; 70 – 42 = 28; 42 – 14 = 28. Answer (c). The correct sequence is 1, 9, 25, 49, 81. The series is made up of squares of all the odd numbers starting from 1. Answer (a). The difference between the consecutive numbers is 21 – 12 = 9; 32 – 21 = 11; 45 – 32 = 13; 60-45 = 15.
