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
