What is the seventh term in the addition pattern that begins 17, 32, 47, 62?

a) 107

b) 117

c) 122

d) 137

A

Step-by-step explanation:

There is a common difference d between consecutive terms of the sequence, that is

d = 32 - 17 = 47 - 32 = 62 - 47 = 15

This indicates the sequence is arithmetic with n th term

= a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 17 and d = 15, thus

= 17 + (6 × 15) = 17 + 90 = 107 → A

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168
