"act" the 3rd and 4th terms of an arithmetic sequence are 13 and 18 respectively what is the 50th term of the sequence

50th term is 248

Step-by-step explanation:

the formula for nth term of arithmetic sequence is

'a' is the first term and d is the constant difference

n is the  nth term

3rd term of arithmetic sequence is 13

Now we plug in 3 for n  in the formula

--------> equation 1

Given 4th term is 18

The difference between 3rd and 4th term is common difference 'd'

18 - 13 = 5

so d= 5

Now we plug in 5 for 'd' in

13= a+ 10

subtract 10 from both sides

a= 3

We know a=3, d= 5  Lets find 50th term
