Anxiety can cause you to overthink what you already know which interns makes you think you don’t know it. Math is just formulas and arthritic and if anxiety has you doubting that you know how to solve a problem then you won’t remember how to solve it

What is a formula for the nth term of the give sequence -3,5,13

kari74 [83]

Step-by-step explanation:

Given sequence is: - 3, 5, 13...

Here first term a = - 3

common difference d= 5-(-3)=13-5=8

Hence, it is in A. P.

Nth term of an AP is given as:

$t_n = a + (n - 1)d \\ \\ \therefore \: t_n = - 3 + (n - 1) \times 8 \\ \\ \therefore \: t_n = - 3 + 8n - 8 \\ \\ \huge \red{ \boxed{\therefore \: t_n = 8n - 11}}$
