Question

70th term of the arithmetic sequence -6, 5, 16, is

Answer 1

Answer:753

Explanation:

The value of
`n^(th)` term can be calculated by,

`T_(n) = a+(n-1)d\\`

where,

a = first number of the series

d = constant difference between the numbers

So, according to the question,

a = -6

d = 11

n = 70

hence, by substituting,

`T_(n) = (-6)+(70-1)11\\T_(n) = 753`
