Question

ALGEBRA

A number pattern is given by the rule: 5n + 1

a) write the first 4 terms of the pattern.

b) Find the 10th term.

Answer 1

a) 6, 11, 16, 21.

b) 51.

Explanation:

5n + 1

a) First 4 terms are 5(1) + 1 , 5(2) + 1, 5(3) + 1. 5(4) + 1

= 6, 11, 16, 21.

b) 10th term = 5(10) + 1 = 51.

Answer 2

Answer and Step-by-step explanation:

5n + 1

n = 1 = 5(1) + 1 = 6

n = 2 = 5(2) + 1 = 10 + 1 = 11

n = 3 = 5(3) + 1 = 15 + 1 = 16

n = 4 = 5(4) + 1 = 20 + 1 = 21

n = 5 = 5(5) + 1 = 25 + 1 = 26

n = 6 = 5(6) + 1 = 30 + 1 = 31

n = 7 = 5(7) + 1 = 35 + 1 = 36

n = 8 = 5(8) + 1 = 40 + 1 = 41

n = 9 = 5(9) + 1 = 45 + 1 = 46

n = 10 = 5(10) + 1 = 50 + 1 = 51
