Answer:

65

Step-by-step explanation:

first term of an AP is 8 i.e. a=8 and its common difference i.e. d=3 and here n= 20

so, its 20th term = a+ (n-1) d

= 8 +(20-1)3

= 8 + 19*3

= 8 + 57

= 65

Answer:

65

Step-by-step explanation:

a=8

d=3

For an AP the n-th term is defined as

n=a+(n-1)d

Therefore 20th term is given as

a+19d

=8+19×3

=8+57

=65
