Answer 2

Answer:

The above questions are of series, which includes number series, alphabet series etc. They have certain rules in which they keep increasing or decreasing$.$

(1) 104, 109, 115, 122, 130

Here the difference is increasing by 1 in consecutive terms. Like +5, +6, +7, +8. So, now it would be +9

• 130 + 9 = 139 (Option C)

(2) 26, 63, 124, 215, 342

Here the rise is irregular but if we observe these numbers, they are nearer to cube numbers. That 26 = 3³ - 1, 63 = 4³ - 1...........342 = 7³ - 1. The numbers are 1 less than cubes of natural number. So, the next number is 8

• 8³ - 1 = 512 - 1 = 511 (Option B)

(3) 15, 31, 63, 127, 255

Here the number are getting doubled and adding with 1. It means for getting the next number, you need to multiply the previous number with 2 and add 1. So, the next number will be:

• 255 × 2 + 1 = 510 + 1 = 511 (Option C)

(4) CDC, EFE, GHG, IJI

Here the first and third alphabets are same and they are in order of the alphabets that is C, D, E..... so on. The odd alphabets are doubling in the first and third place. So, the next alphabets are:

• K and L to be used: KLK (Option A)

(5) KBJ, LCK, MDL, NEM

Here the alphabets at first, second and third place are in sequence as in English alphabet. Like K, L, M....(First place), then B,C,D....(Second place) and then J, K, L.....(Third place). So, the next will be:

• OFN (Option B)

(6) 3, 8, 15, 24, 35

The numbers are 1 less than the square of natural numbers in sequence. The numbers are as 2² - 1 = 3, 3² - 1 = 8.........6² - 1 = 35. So, the next number is 7

• 7² - 1 = 48 (Option C)

(7) 1, 5, 25, 625

The terms are getting multiplied by 5 to get the next term. So, the next number will be:

• 625 × 5 = 3125 (Option B)

(8) Z2, Y4, X8, W16

The alphabets are in backward way as in the English alphabets. And the numbers are in multiplied by 2 to get the next term.

• Next is V and 16 × 2 = 32 = V32 (Option A)

(9) 3, 4, 7, 8, 11, 12

Alternatively the terms are increased by 1 and then increased by 3. Like 3 + 1 = 4 and then 4 + 3 = 7...... Lastly it was 11 + 1 = 12, so now it will add +3,

• 12 + 3 = 15 (Option C)

Finally !! :phew:

(10) WXCD, UVEF, STGH, QRIJ

The first two alphabets are descending order in the English alphabets and the last two alphabets are ascending order in English alphabets. So, the next term is:

• OPKL (Option A)

And we are done !!
