Yohanna is conditioning all summer to prepare for her high school's varsity soccer team tryouts. She is incorporating walking planks into her daily workout plan. Every day, she will complete six more walking planks than the day before. If she starts with two walking planks on the first day, how many walking planks will Yohanna do on the 15th day?

86

Step-by-step explanation:

Since we want to know the number of walking plans that she will do on the 15th day, we have to use 14 days in our calculations as the first day isn't included.

Therefore, the equation to solve this will be:

= 2 + 6d

where,

d = number of days = 14 days

= 2 + 6d

= 2 + 6(14)

= 2 + 84

= 86
