Question

The first three terms of a sequence are given. Round to the nearest thousandth (if necessary). 4,11,18. Find the 50th term.

Answer 1

347

Explanation:

This is Arithmetic Sequence where its common difference= 11-4 = 18-11 = 7

The Geometric Sequence General Formula =
`a_(n) =a_(1)+ d(n-1)`

where a1 is the 1st Term and d is the common difference

`a_(50) =4+7*(50-1)=347`
