Answer 2

Answer:

Step-by-step explanation:

2nd option is correct

a=1,c=3, f=6.

Here the differences are=c-a=3-1=2,f-c=6-3=3

so the second difference is, 3-2=1.

In 2nd,

e=5,h=8, l=12.

the differences of this sequence are=h-e=8-5=3,l-h=12-8=4.

the second difference is, 4-3=1.

In 3rd one= c=3, h=8 and n=14.

Then, h-c=8-3=5,n-h=14-8=6,

the second difference is, 6-5=1.

In 4th one=M=13, we have to find the number whose 2nd difference is 1. Where the two numbers are greater than m. Considering, 2nd option we get. M=13, q=17 and v=22.

q-m=17-13=4,v-m=22-17=5

the second difference is,5-4=1.
