10(5k+2)
14) confused sorry
5(a+2)
4(k+3)
Add the ratio:
2+7=9
747 divided by 9 = 83
Tom -
2x83 = £166
Ben -
7x83= £581
23.
assuming you mean

first term is n=1, so 1²+3=1+3=4
2nd is n=2 so 2²+3=4+3=7
3rd is n=3 so 3²+3=9+3=12
the first 3 terms are 4,7,12
24.
5th term is 5²+3=25+3=28
10th term is 10²+3=100+3=103
difference is 103-28=75
