Answer:

$\sum\limits^7_{n=1}(4n - 3)$

Step-by-step explanation:

Given

$1 + 5 + 9 + .....$

Required

Write a definition

First, we derive a formula for the series using:

$T_n = a + (n - 1)d$

From the attached data;

$a = 1$

$d = 5 - 1 = 4$

So:

$T_n = a + (n - 1)d$

$T_n = 1 + (n - 1) * 4$

$T_n = 1 + 4n - 4$

Collect like terms

$T_n = 4n - 4+1$

$T_n = 4n -3$

So, the definition for first 7 terms is:

$\sum\limits^7_{n=1}(4n - 3)$
