Applying BODMAS (Order of operations rule)
Where: B is for brackets
O is for 'of' which means multiplication
D is for division
M is for multiplication
A is for addition
S is for subtraction
<u>In this case:</u>
We start with addition then we go to addition and finally we subtract.
(78 × 13) - (8 × 78) + (26 × 78) - 78
= 1014 - 624 + 2028 - 78
= 1014 + 2028 - 624 - 78
= 3042 - 624 - 78
=2340
Answer:

Step-by-step explanation:
a1 = 8
a9 = 56
Using formula for finding nth term of arithmeric sequence

We have to find 24th term, therefore n = 24
is the first term but we are missing d
d is the difference between the two consecutive terms, lets calculate it first
a9 = 56
Using the above given formula for finding d
put n = 9, a9= 56

56 = 8 + 8d
8d = 48
d = 6
Getting back to main part of finding 24th term
n = 24, d = 6, a1 = 8
put values in nth term formula
