Question

Calculate the difference between the 10 th term and the 50 th term of the sequence 9 14 19 24

Answer 1

Answer:

200

Step-by-step explanation:

Number series : 9, 14, 19, 24

First term = a1 = 9

common difference = a2 - a1 = 14 - 9 = 5

Find the nth term:

an = a1 + (n - 1)d

an = 9 + (n - 1)(5)

an = 9 + 5n - 5

an = 4 + 5n

Find the 10th term:

an = 4 + 5n

a10 = 4 + 5(10)

a10 = 4 + 50

a10 = 54

Find the 50th term:

an = 4 + 5n

a50 = 4 + 5(50)

a50 = 254

Find the difference between the 10th and 50th term:

Difference = 254 - 54 = 200

Answer: The difference is 200
