Answer 2

FINAL ANSWER:

h = 26

GIVEN:

a=2 , b=6 , c=12 , d=20 , e=30 , f=46 , h=?​

TO FIND:

h=?​

LET'S ASSUME;

2,6,12,20,30,46,?

FORMULA USED:

An=a+(n-1)d

SOLUTION:

An=h=?​

a=2         (first term)

n=7         (term which we have to find)

d=a2 - a1    =6 - 2 =4

∴ An=a+(n-1)d

   A$7$=2+(7-1)4

   A$7$=2+(6×4)

   A$7$=2+24

   A$7$=26

     h=26
