Answer 2

Answer:

We should find the logic between each terms.

Final Answers: 1) $19,21,24,28,37,53,78$

                         2) $8,9,15.5,34,89, 272$

                         3) $28, 34, 44, 58,76 ,98, 124$

                         4) $23, 21, 24, 20, 25, 19$

Step-by-step explanation:

1. 19,21,24,28,37,53,?

Logic: we should find the difference of difference

$19+2=21$

$21+3=24$ → (Difference between $2$ and $3$ is $1$)

$24+4=28$ → (Difference between $3$ and $4$ is $1$)

$28+9=37$ → (Difference between $4$ and $9$ is $5$) → (Difference between $1$and $5$ is $4$)

$37+16=53$ → (Difference between $9$ and $16$ is $5$)

$53+25=78$ → (Difference between $16$ and $25$ is $9$) → (Difference between $5$ and $9$ is $4$)

Answer: 19,21,24,28,37,53,78

2. 8,9,15.5,34,89, ?

Logic: Multiplication and Addition of $1, 1.5, 2, 2.5, 3$.

step 1:Take the first term should multiply by 1 and add with 1

$(8*1)+1=9$

step 2:Then add step 1 answer and 0.

$9+0 = 9$  

step 1:Take the second term should multiply by 1.5 and add with 1.5

$(9*1.5)+1.5 = 13.5=13.5+1.5=15$

step 2:Then add step 1 answer and 0.5

$15+0.5=15.5$

step 1:Take the third term should multiply by 2 and add with 2

$(15.5*2)+2=31+2=33$

step 2:Then add step 1 answer and 1

$33+1=34$

step 1:Take the fourth term should multiply by 2.5 and add with 2.5

$(34*2.5)+2.5=85+2.5=87.5$

step 2:Then add step 1 answer and 1.5

$87.5+1.5=89$

step 1:Take the fifth term should multiply by 3 and add with 3

$89=(89*3)+3=267+3=270$

step 2:Then add step 1 answer and 2

$270+2=272$

Answer:  8,9,15.5,34,89, 272

3. 28, 34, 44, 58,76 ,98, ?

Logic: Difference of difference is 4

$28+6=34$

$34+10=44$ → (Difference between 6 and 10 is 4)

$44+14=58$ → (Difference between 10 and 14 is 4)

$58+18=76$ → (Difference between 14 and 18 is 4)

$76+22=98$ → (Difference between 18 and 22 is 4)

$98+26=124$ → (Difference between 22 and 26 is 4)

Answer:  28, 34, 44, 58,76 ,98, 124        

4. 23, 21, 24, 20, 25, ?

Logic: Subtract even position numbers by 1.

Even position numbers: 21,20,?.

$21-1=20$

$20-1=19$

So that next number is 19.

Answer: 23, 21, 24, 20, 25, 19
