Find a formula for the nth term

vlada-n [284]

The formula for a sequence with first term = 1.7 and common difference 0.5 is: $a_n = 1.2 + 0.5n$

Step-by-step explanation:

The first term and common difference are used to induce a formula for the arithmetic sequence

The explicit formula for a geometric sequence is:

$a_n = a_1+(n-1)d$

Given

First term = a1 = 1.7

Common Difference = d = 0.5

putting the values in the formula

$a_n = 1.7 + (n-1)(0.5)\\a_n = 1.7 + 0.5n-0.5\\a_n = 1.2 + 0.5n$

The formula for a sequence with first term = 1.7 and common difference 0.5 is: $a_n = 1.2 + 0.5n$
