Question

Write an arithmetic sequence with first term 5 and common difference 4 . Write its algebraic expression​

Answer 1

Answer:

here

first term a = 5

common difference d = 4

required AP is,

t2= a+d = 5+4=9

t3= a+2d = 5+2×4= 5+8= 13

t4= a+3d = 5+3×4 = 5+12= 17

hence required AP is 5,9,13,17,21...
