Question

FIND THE nth term of the following

A =7,12,17,20

B=5,9,13,17​

Answer 1

Tn =4n+1

Explanation:

A. T1 = 7 Rule: add 5

T1 = (5×1) +2 =7

T2 = (5×2)+2 = 12

T3 = (5×3)+2 = 17

T4 = (5×4)+2 = 22

B. T1 = 5 Rule : add 4

T1 = (4×1)+1 = 5

T2 = (4×2)+1 = 9

T3 = (4×3)+1 = 13

T4 = (4×4)+1 = 17

Tn = (4×n)+1 = 4n+1
