Question

Find the 56th term if A1=23 and the cd=-7

Answer 1

Salutations!

finding the 56th term is same as find the nth term, but its a bit more easier than finding the nth term.

we'll be using a formula to find the fifth term.

$a+(n-1)*d$

$a$ stands for the first term (the first number in a sequence)

$d$ is the difference between the constants 

$n$ is the what will be finding

so instead of n, we will be plugging in the number 56.

$a+(n-1)*d$

$23+(56-1)*-7$

we will be solving the brackets first

$23+55*-7$

$78-7$

=71

the 56th term is 71

hope this helps!

have a great day!
