The nth term of a sequence is 3n+2

a) work outh the first three terms of the sequence

b) work out the tenth term of the sequence

An arithmetic sequence is a set of numbers with a common difference.

Given

The first three terms

When

When

When

So, the first three terms are 4, 7 and 10

The tenth term

When , we have:

Hence, the tenth term is 31

Step-by-step explanation:

Given the n th term formula.

To find the first 3 terms substitute n = 1, 2, 3 into the formula

(a)

= (3 × 1) + 2 = 3 + 2 = 5

= (3 × 2) + 2 = 6 + 2 = 8

= (3 × 3) + 2 = 9 + 2 = 11

The first three terms are 5, 8, 11

(b)

Substitute n = 10 into the formula

= (3 × 10) + 2 = 30 + 2 = 32

The tenth term is 32

step-by-step explanation:

25 questions , because they start with 100.  

350-100=250 .  

. 250/10=25

step-by-step explanation:

first take off 100, then what x 10 = 250? that is your answer. (25)
