                         4) [tex]23, 21, 24, 20, 25, 19[/tex]

Step-by-step explanation:

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

Logic: we should find the difference of difference

[tex]19+2=21[/tex]

[tex]21+3=24[/tex] → (Difference between [tex]2[/tex] and [tex]3[/tex] is [tex]1[/tex])

[tex]24+4=28[/tex] → (Difference between [tex]3[/tex] and [tex]4[/tex] is [tex]1[/tex])

[tex]28+9=37[/tex] → (Difference between [tex]4[/tex] and [tex]9[/tex] is [tex]5[/tex]) → (Difference between [tex]1[/tex]and [tex]5[/tex] is [tex]4[/tex])

[tex]37+16=53[/tex] → (Difference between [tex]9[/tex] and [tex]16[/tex] is [tex]5[/tex])

[tex]53+25=78[/tex] → (Difference between [tex]16[/tex] and [tex]25[/tex] is [tex]9[/tex]) → (Difference between [tex]5[/tex] and [tex]9[/tex] is [tex]4[/tex])

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

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

Logic: Multiplication and Addition of [tex]1, 1.5, 2, 2.5, 3[/tex].

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

[tex](8*1)+1=9[/tex]

step 2:Then add step 1 answer and 0.

[tex]9+0 = 9[/tex]  

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

[tex](9*1.5)+1.5 = 13.5=13.5+1.5=15[/tex]

step 2:Then add step 1 answer and 0.5

[tex]15+0.5=15.5[/tex]

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

[tex](15.5*2)+2=31+2=33[/tex]

step 2:Then add step 1 answer and 1

[tex]33+1=34[/tex]

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

[tex](34*2.5)+2.5=85+2.5=87.5[/tex]

step 2:Then add step 1 answer and 1.5

[tex]87.5+1.5=89[/tex]

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

[tex]89=(89*3)+3=267+3=270[/tex]

step 2:Then add step 1 answer and 2

[tex]270+2=272[/tex]

Answer:  8,9,15.5,34,89, 272

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

Logic: Difference of difference is 4

[tex]28+6=34[/tex]

[tex]34+10=44[/tex](Difference between 6 and 10 is 4)

[tex]44+14=58[/tex] (Difference between 10 and 14 is 4)

[tex]58+18=76[/tex] (Difference between 14 and 18 is 4)

[tex]76+22=98[/tex] (Difference between 18 and 22 is 4)

[tex]98+26=124[/tex] (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,?.

[tex]21-1=20[/tex]

[tex]20-1=19[/tex]

So that next number is 19.

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