The diagram below represents the first three terms of a sequence. assuming the pattern continues, which formula determines an, the number of squares in the nth term ?

We will count number of squares

first term is 4

so,

second term is 7

so,

third term is 10

so,

We can see that this sequence is in arithematic sequence

we can use nth term formula

where

an is nth terms

a1 is first term

d is common difference

n is total number of terms

now, we can plug values

and we get

.................Answer

answer: do you still need this?

the first question mark is 6 and the second question mark is 26 (the square root)
