Arithmetic Sequence
The value of the 20th term of this arithmetic series is 136
Step-by-step explanation:
The first term of the arithmetic term is a = 3
and the common difference is d = 7
So the 20th term of this arithmetic progression is given by
an = a + (n-1) × d
where an is the nth term of the arithmetic progression
so for nth term, the value of n = 20
⇒ a20 = 3 + (20-1) × 7
⇒ a20 = 3 + 19 × 7
⇒ a20 = 3 + 133
⇒ a20 = 136
Hence ,the value of the 20th term of this arithmetic series is 136
