Write down the expression for the nth term of the following sequence 7,16,25,34,43 the following patterns are made using small squares write down an expression forthe number of small squares in pattern n

this is an arithmetic sequence. The formula to solve it is an = d (n - 1) + c

Step-by-step explanation:

you would plug in the first term in the sequence for d. then you would plug in the common difference for c. And then lastly you would plug in whatever nth term you are trying to get to for n. Then solve.

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)
